The Power Catamaran Compilation

• By Yachting Staff
• Updated: December 21, 2018

Power Catamarans have been growing leaps and bounds in popularity, and, in lengths and widths. And for good reason. These cruise-centric yachts offer homelike livability for avid travelers, are fuel efficient and are fairly intuitive to run. Power cats are popular in the bareboat charter market too, for these very reasons.

Here, we take a look at 12 catamarans ranging from a cruising-couple-size 36-footer to a 78-footer for friends, family and some more friends. And there are myriad power options: outboards, diesel inboards, hybrid or even all-solar power.

Fountaine Pajot MY44

The Fountaine Pajot MY44 , a creation of Italian architect Pierangelo Andreani and French designer Daniel Andrieu, has a main deck that’s open from the aft-deck seating all the way forward to the starboard helm station. The sense of spaciousness is significant, for several reasons. First, four glass panels aft can all slide to port, creating an indoor-outdoor space with the aft deck and salon. In the salon, 32-inch-high windows extend for 12 feet down the sides of the yacht, with three sections per side, bringing in natural light along with the three forward panes that comprise the windshield. Finally, 6-foot-6-inch headroom provides vertical clearance, with a 21-foot-7-inch beam that adds interior roominess while keeping the yacht stable.

Silent-Yachts 55

The ideas about which solar panels, electric motors, inverters and the like to use — and more importantly, Michael Köhler says, how to configure them — became the basis for the brand Silent-Yachts. The company offers 55-, 64- and 79-foot catamarans that run on solar-electric propulsion. The Silent 55 premiered this fall, and the 64 is sold out for the next two years, Köhler says.

Horizon PC74

As founder and director of The Powercat Company, a Horizon Power Catamarans distributor, Stuart Hegerstrom had long believed that catamaran builders needed to design their yachts to more stylish standards.

“The boats were very boxy,” he says, based on his years of experience with cats in the charter market. He and his partner, Richard Ford, asked Horizon to produce models that had high-end finishes and looked good inside and out.

The Horizon team brought in mega-yacht designer JC Espinosa to work with its own craftsmen. The result aboard the Horizon PC74 is a catamaran with exterior styling, layout and functionality that should appeal to private and charter owners alike.

The Aquila 36 is a departure from her sisterships in that she is an outboard-powered, express-cruiser-style catamaran, but she also adheres to MarineMax’s philosophies.

With a single main living level from bow to stern and a beam of 14 feet 7 inches, the Aquila 36 is like a bowrider on steroids. She has seating that can handle 20 adults for outings and barbecues, and there are two staterooms below, one in each hull, for family weekending. The staterooms have nearly queen-size berths, en suite heads, stowage and 6-foot-6-inch headroom.

Lagoon Seventy 8 Powercat

Lagoon is a division of Groupe Beneteau, the world’s largest builder of sailing yachts, and the Lagoon Seventy 8 Powercat is a developmental sistership of its Seventy 7 super sailing cat. The Seventy series yachts are built at Construction Navale Bordeaux in France, which had to add a new yard to construct these catamarans because they require separate stern molds for the power and sail versions.

Horizon PC60

To understand the Horizon PC60 power catamaran , you need to put aside preconceived notions about midsize yacht amenities. For example, main-deck master suites are the province of yachts over 100 feet length overall. Incorrect. This 60-footer has an elegant and spacious owner’s stateroom on the same level as the salon. If you want a 14-foot center console tender on a 60-foot yacht, you have to tow it. Wrong again. On the PC60, you hoist it onto the upper deck, no problem.

40 Open Sunreef Power

Sunreef is known for pushing the boundaries of catamaran design, incorporating four adjustable hydrofoils into a twin-hulled speedboat.

The Polish builder is one of several European builders (including Evo, Fjord, Wider and Wally) transforming the open ­day-boat category with creative designs. ­Beyond its hydrofoils, the 40 Open Sunreef Power ‘s cockpit has side “wings” along the aft gunwales that fold out at anchor, widening the beam from 17 feet to 22 feet 9 inches.

Sunreef 50 Amber Limited Edition

Sunreef Yachts introduced its 50 Amber Limited Edition , with plans to launch just 10 hulls of the exclusive design.

The Sunreef 50 Amber Limited Edition will have a carbon fiber mast and boom, four layout options and numerous amber-colored elements, including the hull.

Lagoon 630 Motor Yacht

Fitted with the optional twin 300-horsepower Volvo Penta D4 diesels, the Lagoon 630 MY burns only 1.64 gph total at 6 knots, giving a theoretical range of 2,952 nautical miles with standard tankage of 793 gallons. Hull No. 1 had an optional 502-gallon tank, giving it transatlantic range.

Luxury, stability and economy are all hallmarks of Lagoon’s return to luxury motor yachts. If you can take a ride, it will be worth your time.

Fountaine Pajot MY 37

The Fountaine Pajot MY 37 easily accommodates the seafaring family with three- and four-stateroom options. In the three-cabin version, called ­Maestro, you’ll find an owner’s suite in the portside hull with a queen-size berth and en suite head. Two double-berth cabins and one more head are available for the kids. If your brood is bigger, the Quator setup features four double cabins with two heads.

The 37 is a traveler and can be powered with twin 150 hp or 220 hp Volvo Penta diesels. Top speed with the smaller engines is 17 knots, while it’s 20 knots with the bigger power plants. Interestingly, at 7 knots, the fuel consumption is the same, with either set of motors offering voyagers a 1 ,000-nm range.

Solarwave 64

Many yachts boast eco chops because they have a handful of solar panels that power the microwave or navigation lights. The Solarwave 64 , launched last summer, has the potential to run on sunshine alone. The vessel’s 42 solar panels generate 15 kW that are stored in batteries weighing about 1,300 pounds. They connect to electric motors.

Glider SS18

This British builder says it strives for design innovation and the Glider SS18 displays that DNA, the result of 8 years of research and development. She has a head-turning, catamaran hull form constructed from aluminum and composite materials. She is 60 feet LOA with a 17-foot beam, and has a relatively shallow 1-foot draft. Powered by quad Yamaha 300 hp outboards, she can reportedly reach 50 knots, and with her Stability Control System (SCS), should give a smooth ride while doing it.

Find Out What Sets Aspen Power Catamarans Apart

Modern power catamarans come in many different styles and configurations. Benefits of catamaran designs typically include increased stability, deck space, ride, and cruising efficiency. At Aspen we think differently and refined the concept further by developing a unique PRO cat that maximizes fuel efficiency and range while improving ride and seaworthiness.

Patent No. US 8,109,221 B2

Check out the latest Aspen Innovation: The Aspen Carbon Cat tender.

Matchless efficiency and performance.

Aspens offer all the advantages of a catamaran, but in a design that can use a single, efficient diesel inboard or two outboards of different horsepower.

True Innovation in Design

The Aspen hull design offers the stability and space of a catamaran, but tracks straight with a single diesel inboard or two outboards of different horsepower.

A Thirst for Adventure

Because Aspen owners tend to go on long trips exploring remote areas, we have included a double-bottom construction method.

Intelligent Interiors

Thanks to the dual hull design, every Aspen has interior room comparable to that of a monohull that is 25 percent longer, but it’s what we do with that space that sets us apart.

Built with Care

The composites used in the construction of an Aspen power cat are a thoughtful balance of modern high technology, using premium Vinylester and Isophthalic resins, S-glass, Kevlar, and cross-linked PVC cores ranging in thickness from a quarter-inch all the way up to 2 1/2 inches.

Who Makes The Best Power Catamaran?

By Robert Bowman | Posted On Sep 15, 2022 Updated On May 03, 2023

The story of the evolution of the power catamaran can be broken down to a simple act of marital duty. it was the 1940's and Ray Leger loved to fish off of the California coast with his wife Evelyn. Ray had been a carpenter and capitalized on the booming Southern California housing market after World War 2, later using his skills and equipment to construct fishing boats. Evelyn would routinely suffer from seasickness, a problem that Ray needed to solve in order to keep fishing. Knowing that a catamaran offered greater stability, Ray set out to build one with outboard motors. The first one, an 18-foot cabin cruiser, was outfitted with twin 33hp outboards. By the 1960's, construction had moved to fiberglass hulls and the popularity quickly soared.

Today, power catamarans are among the fastest growing segments in the marine industry, as are sailing catamarans . A recent report shows that the global catamaran market as a whole is worth over $4 billion and has an annual growth rate of over 6%. That's nearly double what the average CAGR (compound annual growth rate) is for the boating industry in total.

The transition to power cats really came from charter customers in the Caribbean that would vacation on sailing cats in the BVI's for weeks at a time. The catamarans offered greater stability, but also an incredible amount of space on board thanks to the wider beams. But people on vacation enjoying the trip would end up using the small engines most of the time as sailing comes with a certain amount of effort. Now it's common to see power catmarans in charter in the Caribbean, as well as privately owned boats behind someone's house.

As more boaters get exposed to the benefits of power catamarans, the number of builders has grown as well. Power cat brands like Aquila Boats , as an example, weren't around in the early 2000's, but are now a common boat to see all over Florida or the Northeast. Prestige Yachts also just released their very first power cat into the market, the M48. Trying to claim that one power catamaran builder is the "best" among all of the others is a tough decision as there are many factors. If judged by number of units sold over the last 10 years, then Leopard is the best power catamaran builder in the industry. Looking at boats sold globally in the MLS over the last decade, Leopard Catamarans sold 40% more vessels than the second leading power cat builder, Fountain Pajot . Other notable power cat brands that led in overall sales were Endeavor, Lagoon, and Aquila.

(Below: On the extreme luxury power catamaran market, the Sunreef 80 is among the best.)

While the number of boats sold into the marketplace is a sign of strength in a builder, it also may not necessarily equate to 'being the best power catamaran' in terms of quality. Like with monohulls, there are varying degrees of both quality and price when it comes to the subsects of the power cat industry. Both Sunreef and Horizon Yachts have expanded into large luxury power cats that, even when more than 10 years old, can still command more than $2 million as an asking price.

One way to tell if the catamaran you're buying is well-recognized for its quality is to look at some of the recent award winners. Many of the editors of multi-hull focused magazines are experts in this category and have real-life experiences on dozens of different models. Here are a few notable ones:

• Fountaine Pajot MY4.S won the 2022 Multi-Hull of the Year Award for its category (36.1' and reaches 22 knots!)
• The Aquila 54 won 2021 Multi-hull of the Year 
• The Leopard 53 Power Cat won 2020 Multi-Hull of the Year
• The Lagoon 55 won the 2021 British Yachting Awards

(Below: The new Fountaine Pajot MY4.S offers a new 'sport top' style for the longtime catamaran builder.)

Whether you're purchasing a new or pre-owned power catamaran, its resale value is of the utmost importance. Nothing can stifle your enthusiasm when you are trying to sell your existing yacht only to have it sit on the market for a long time while diminishing in value. If this is of concern to you, the best advice is to stick with the more mainstream, reputable catamaran builders. Boats with odd layouts, underpowered engines, outlandish decor, and other out-of-the-norm equipment can cause your boat to sit on the market longer than anticipated.

The market demand has also improved in recent years. Over the last decade, power catamarans took roughly 330 days to sell. Almost a full year! Since 2020, however, that amount of time has decreased by 19%. Among the builders that sold within 100 days of hitting the market, Aquila, Endeavor, Fountaine Pajot, Leopard, and Robertson & Caine were prominent. 

(Below: The Aquila 54 Power Catamaran has a tri-deck design with a beam of over 25-feet.)

9 Best Power Catamarans For Rough Seas and Coastal!

As an Amazon Associate, we earn from qualifying purchases. We may also earn commissions if you purchase products from other retailers after clicking on a link from our site.

Power catamarans are gaining popularity in the cruising world thanks to their enhanced stability and ease of operation. They’re ideal for coastal cruising but can also be used for ocean crossing thanks to their stability and speed.

Here are some of the best power catamarans on the market:

• Fountaine Pajot MY6
• Nautitech 47 Power
• Horizon PC74
• Lagoon Seventy 8
• ArrowCat 420
• Sunreef Supreme 68

In this article, I’ll review some of the best power catamarans out there. I’ll also go over the main features of different power cats and if they can handle rough weather. 

But before we dive in, let’s get a better understanding of what power cats are.

Table of Contents

What Is a Power Cat?

A power catamaran (power cat) is a motor-powered boat that, unlike traditional boats, has two hulls connected by a bridge deck. These vessels are more stable than monohulls because of their wide base.  

Power cats also don’t have a leaded keel to weigh them down, so they’re pretty lightweight and fast. The lack of a keel also means that power cats are more suitable for shallow waters.

They feature large engines designed to handle their bigger bodies and weights, and serve different purposes, like fishing, cruising, or crossing rough seas. In addition, each hull has a separate engine which makes them more maneuverable, especially at turns and tight spaces.

Power catamarans don’t have sails or masts and get all of their power from the combustion engine (or electric motor), unlike their sailing cousins. In addition, these vehicles are much easier to steer because of their increased stability.

Power catamarans have more interior and exterior space thanks to their multihull design, making them perfect for cruising and liveaboard . They also have ample space for storing everything you need on a cruise without worrying about weighing it down. Catamarans offer increased privacy as well because each hull houses one sleeping area, separated by the living area between them.

Are Power Cats Good in Rough Water?

Power catamarans are good in rough waters particularly because of their multi-hull design. Their wide base makes them stable, and their high speed allows for outrunning bad weather.

Power cats that feature a high bridge clearance, will handle rough waters effortlessly. With the added height, you won’t experience pounding and slamming even in heavy waves, allowing the crew to easily control the vessel in challenging situations.

These boats are also faster than their sailing counterparts, which means they can get you out of rough waters quickly.

In addition, since catamarans are large and tall, maneuvering is easier because you have a better view of the surroundings. Additionally, you can steer from the interior cockpit (on certain models), making it easier to control the vessel in bad weather.

Finally, although a power cat doesn’t have a keel to help it right itself in case of capsizing, it will still float easily because of its positive buoyancy.

Are Power Catamarans More Efficient?

Power catamarans are more fuel-efficient than monohulls because they don’t have leaded keels. While keels are designed to offer stability by weighing down the vessel, they increase the wetted surface and thereby add drag.

Due to the catamarans’ narrow bow entry, there’s lower resistance, leading to smoother acceleration and greater fuel economy in catamarans. In addition, power cats show fewer spikes in fuel consumption in a single power band, especially because of their smooth acceleration and fuel consumption.

The figures reported by cat owners or manufacturers show that power cats have the best power-consumption-to-speed ratios.

That being said, you can improve fuel efficiency by maintaining lower speeds; studies have shown that speed can be the most important factor in fuel efficiency, regardless of the number of engines or hull types. 

Now that you have a better understanding of power catamarans, let’s take a look at the ten best models on the market.

1. Leopard 53

This 53ft (16.19m) power cat is the fourth generation of the widely popular Leopard catamarans, and brings with it all the great features from her predecessor, the 51. 

Although the 51 was the company’s best-selling cat, they added these features to the 53 along with new ones to repeat its success. For example, they have built an enormous saloon, flybridge, and galley by removing the foredeck cockpit in the 51 PC, making it 30 percent larger than the previous model.

This model comes with three or four stateroom layouts, with the 3-stateroom version featuring an owner’s stateroom, two sinks, a loveseat, and lots of storage space.

With two Yanmar 370 hp engines, a maximum speed of 22 knots, and a cruising speed of 17.5, you can enjoy a magnificent ride, whether it’s long-distance cruising or a fun night out with friends.

2. Fountaine Pajot MY6

This luxury power cat is 44ft (13.40m) long, making it super spacious and suitable for families and big parties. With its spacious flybridge, sunbathing lounge, and enormous galley, it’s nothing short of a second home on the water. 

You can steer the cat from the saloon or the 21sqm (68 sq ft) flybridge which features a sunbathing lounge, a pool, and a galley.

This motor yacht continues to delight with its luxurious combination of privacy and pleasure, with views of the sea in almost every interior space. With three cabins, two bathrooms, six cabin beds, ample storage, and a kitchen that opens into the cockpit, you can enjoy practicality and luxury in one place.

The MY6 is exceptionally seaworthy and stable thanks to its wave-piercing hulls and Volvo IPS engines.

Like all power cats, it has straightforward steering, enabling you to control this beast even in the roughest circumstances.

3. Nautitech 47 Power

Powered by dual Volvo Penta D4 engines, this model can output 225-300hp, reaching a maximum of 22 knots and a cruising speed of 18-20 knots . This 46′ 8″ (14.23m) long power cat comes in three or four cabin versions, depending on the customer’s preference.

No matter which layout you choose, you’ll get a spacious, luxurious, and comfortable catamaran with panoramic views from the cabin. The sleek, streamlined exterior design ensures elegant sailing and seaworthiness.

It’s easy for passengers to navigate the deck thanks to its seamless design that connects the saloon to the cockpit and the rear deck. The stern features a big swimming platform that can also accommodate a tender. The cockpit is usable in different weather conditions thanks to the clear covers wrapping the whole area.

This efficient catamaran promises long cruising for big families and groups with two 300L water tanks and a pair of 645L fuel tanks.  

4. Horizon PC74

The Horizon PC 74 is another luxury power cat that can give you the comfort of your home on water. This 73′ 9” (22.48m) long power cat with a 2,000gal (7570L) fuel tank is an enormous vessel that can accommodate more than 14 people.

The enormous hardtop on the three-piece windshield, the teak dining table, the U-shaped bar, the sun pad, and the swing-out stools all guarantee that you’ll have the luxury cruising experience of a lifetime.

This vast and wide catamaran allows you to access the aft deck from the flybridge via a curving staircase. The vast aft deck has a ten-person dining table, a wet bar, and storage space. You can separate the interior and exterior spaces through sliding glass doors and make the space appear bigger by opening them.

Reaching a top speed of 23 knots and a cruising speed of 19 knots, this enormous catamaran was built for efficiency and practicality.

5. Lagoon Seventy 8

This 78’1″ (23.80m) power cat with two 494 HP engines and a 2246gal (8500L) fuel capacity is one of the largest power cats on the market, offering both comfort and reliability. The enormous flybridge can feature a jacuzzi, a sunbathing area, a large foldable dining table, and a hardtop with a moveable roof. However, you can customize the flybridge based on your preferences.

The designers have compromised nothing in terms of elegance and high-quality materials with top-of-the-line finishes and interior paneling to create the kind of luxury you want.

The saloon is huge, well-ventilated, and separated from the exterior by glass doors and panoramic windows.

But what sets Lagoon Seventy 8 apart from other power cats, in addition to its enormous size, is the wide choice of layouts. You can choose between five different versions, all offering the same amount of storage space, living and sleeping area, and privacy.

Additionally, some versions are fully customizable, allowing you to pick every detail to your liking.

6. ArrowCat 420

This 41′ (12.73m) long express cruiser is a semi-custom catamaran with two-stateroom and three-stateroom layouts. The ArrowCat 420 is designed and built with comfort and strength in mind, and capable of handling rough waters safely.

The two Suzuki 350 hp engines give this model a maximum speed of 40 knots and a cruising speed of 20 knots.

The streamlined design and the angled hulls ensure the vessel cuts through the waves effortlessly, making it easy to maneuver.

The fully-equipped head features an electric toilet, a shower, sink, and mirrors, coupled with a dining table, floor storage locker, and teak-finished floors. This cat is built to combine luxury and comfort for both onshore and offshore cruising.

7. Bali 4.3

This 43′ (13.1m) power cat is made for ocean crossing in mind. With five different layouts featuring different combinations of cabins and heads, the company ensures you’ll get the kind of setup you want. Regardless of the layout, this cat offers a spacious master suite with a large double bed and other private sleeping quarters.

You can quickly add to the overall space by removing the adjustable glass doors to merge the cockpit with the saloon.

A feature that sets the 4.1 apart from its predecessor is the fixed aft deck between the hulls, which provides a passageway and eliminates the need to go from one hull to the other without entering the cockpit.

8. Sunreef Supreme 68

According to its designers, this model was built with a radical concept in mind while staying true to the company’s promise of building the most comfortable and spacious power cats in the world.

One of the greatest features of the Supreme 68 is its aft garage that houses a 5m (16 ft) tender and two jet skis in addition to other water toys.

You can also transform the aft to a large platform for water sports by lowering the garage door.

The four-stateroom layout features ample storage, ensuite guest cabins, queen-sized beds, and TVs to create a memorable stay. The white and beige furniture with chrome details and floor-to-ceiling glazing create a soothing atmosphere that blends with the practicality of the well-equipped galley. 

However, if you’re looking for something different, you can opt for a customized model from three different layouts.

9. Hudson 48

The sleek, diamond-cut design of this 46.46’ (14.16m) long power cat is usually the first thing to catch your eye.

It’s a light displacement cat that ensures fast cruising with a top speed of 24 knots and cruising speed of 8 knots thanks to the two 370hp Yanmar V8 engines.

The three-cabin layout features a master stateroom with a spacious and well-ventilated design made possible via the three overhead windows and opening deck hatches.

The saloon’s enormous helm station allows for comfortable and safe accommodation, making it great for rough waters and bad weather conditions.

This model also offers a few entertainment options with its large TV systems and mood lighting. The storage areas and the full-sized walk-in wardrobe give this model a comfortable, homely setting.

How to improve power management on a yacht

• August 21, 2024

Mike Morgan offers advice on how to improve power management on a yacht and preserve precious amps for those that like their home comforts

I confess, I’m not a marine electrician, and my understanding of boat electronics is at best rudimentary, but I’ve now been managing my boat’s power generation and consumption for three seasons and have developed an approach which seems to work well. Hopefully, you will find some of the following advice useful when it comes to managing your own yacht’s energy needs.

Every boat has its own particular balance of power generation and demand, so my system may not work perfectly for you, but it might help you start managing your precious amps a lot more effectively.

My wife Debbie and I sail up to nine months a year around the Med, predominantly lying at anchor. We avoid marinas and use our generator infrequently, to help save the planet and our budget.

I won’t address power needs whilst under sail here, as it’s not relevant to our cruising profile. Clearly, if you’re taking on an Atlantic crossing , then you’ll need to consider the power demands from your navigation equipment, lights and auto pilot.

We bought our pride and joy, Spirit, a Bavaria C57, brand new in 2021, and made several upgrades in an attempt to achieve the holy grail of self-sufficiency at anchor. We opted for 800 amp hours (Ah) hours provided by lithium batteries that weigh less than a single 150Ah lead acid battery.

Because lithium offers roughly twice the capacity of lead acid, that’s equivalent to 16 100Ah lead acid batteries with a combined weight of just over a third of a ton. Given Spirit’s generous beam, we’ve been able to accommodate four 420W solar panels, giving a potential maximum of 1,680W.

State of charge

The amount of electrical power you have available is all about batteries. Boat batteries are usually measured in amp hours (Ah) – the total number of amps devoured in one hour of use. So, a 120Ah battery will, theoretically, deliver 120A for one hour or 1A for 120 hours. But, of course, this is a little simplistic.

If you have lead acid batteries, you must never completely discharge them, unless you want to replace them regularly. Lead acid batteries should never be discharged below 50 per cent, so the practical Ah they really offer is half the theoretical Ah rating. In the above example, 60 hours at 1 amp would be the limit before you had to recharge the battery. Typically, the state of a battery’s charge is monitored by volts or a shunt battery monitor.

Knowing the state of charge of your batteries is critical to managing your power needs.

How to get your yacht home without power

Electrical systems and electronics have become such an essential part of our normal lives that it’s hard to imagine life…

Everything you need to know about yacht solar power

Keeping your batteries topped up without having to run the engine is a continuous challenge for cruising sailors, especially those…

I replaced our Bavaria’s standard 240Ah of domestic lead acid batteries with 800Ah of lithium batteries. The advantage of a lithium battery is its light weight. And, unlike a lead acid battery, it can be run down to a much lower charge. The downside is that lithium batteries have been known to explode.

To avoid this, they need to be paired with a battery management system, which is best left to a professional, who knows what they are doing, to install.

Charging sources

A standard ‘off the shelf’ mid-size production boat is likely to be fitted with a 60A battery charger which is used by the boat’s generator, if it has one, or when shore power is plugged in. The engine will also have an alternator which will typically produce between 35 and 60A of charge, depending on the size of the engine.

Assuming a 60A charge source, the batteries will receive 60A of charge in one hour. So, to put it very simplistically, if you have, as I do, 800Ah of lithium batteries and they are at 50 per cent, to charge them up to capacity would take 6.6 hours (400 amps divided by the charging source of 60 amps equals 6.6 hours).

Unfortunately, it’s not quite as simple as that. For example, there are various charging states – bulk, absorption and trickle (also known as maintenance or float) – and different types of batteries with different ratings, but I have kept it as simple as possible here for the purposes of explanation.

If you don’t have shore power (when at anchor, for instance), or don’t have a generator, the alternative is to run your engine for six hours under light load, which is not good for the engine and won’t win you many friends nearby who are trying to relax and enjoy a peaceful sundowner.

Battery charger

Increasing the size of your battery charger will speed up the process of charging from both a generator and shore power. I opted to fit a 120A charger and a 3kW inverter for my 240V appliances. There is always the option to beef up the engine alternator to feed a hungry family of batteries, but again, this means the boat engine needs to run for prolonged periods of time.

The 9kW Paguro 9000 generator I fitted produces a lot more power than we ever need. The generator powers both the 240V ‘ring main’ and the battery charger. However, the battery charging will be limited by the power rating of the charger, which in my case is 120A.

Four solar panels on Spirit’s stern arch produce a maximun 1,600W

Renewable energy

Renewable energy for boats is either wind, hydro or solar. I opted for solar on a custom-made stern arch. I fitted four 400W panels, which produce a theoretical maximum output of 1,600W at 12V or, in amp speak, 133A.

Like lithium batteries, the voltage and charge from solar panels needs to be managed, so each panel is equipped with an MPPT (maximum power point tracking) controller to ensure the batteries are getting the right amount of charge when the sun is shining. The next conundrum was to get all this in perfect balance based on the boat’s power consumption.

The stern arch was custom-built to support the solar panels

Background noise

I started by building a spreadsheet to calculate the various power ratings of my many onboard electrical appliances. However, this isn’t simple as you must calculate the power demand of each appliance, estimate how long you will run it for, and when you will run it.

You then need to map this over time to calculate a theoretical power demand and how much power you need to be generated. Estimating the power output from my solar panels alone became a headache: calculating the assumed number of ‘sunny’ daylight hours, the angle of the sun, solar panel efficiency, and when the next solar eclipse would be! So, like all people with limited brain capacity, I gave up.

I decided, instead, to take a more pragmatic approach. The first thing I did was to measure the ‘background noise’ of my boat; that is, the power being consumed whilst at anchor and not running any major appliances.

It turned out to be around 200A, which is very high; but then I do have three fridges, a deep freeze and more internal lighting than Blackpool Illuminations.

The time it takes to recharge my batteries once the sun has dragged itself up to the right angle differs dramatically based on which way the boat is lying. If my stern is exposed to the sunny side my batteries will fill to the brim in a few hours. However, if my bow is facing the sun, it takes a lot longer.

On an average day, we are at 100 per cent by midday or early afternoon, leaving a good four or five hours of surplus power generation for running more critical systems.

Air-con is a battery power ‘killer’

We have a lot of power consuming paraphernalia on board, for example the kettle, coffee maker, hair dryer, microwave oven, and so on, but I ignore these when it comes to power management as they are used randomly and are never on for long.

However, we do have several appliances that are critical to our power management, including a washing machine, water maker, ice maker and water heater. All of these have high demand and can run for long periods of time. I also have air-conditioning which can be run off the inverter, but I prefer to use fans and open hatches to keep the temperature tolerable when we are at anchor. Air-con is a battery power killer and is best left to when shore power is connected or the generator is running.

Our Bavaria came with a built-in utility room, so we decided to fit a full-sized washer-dryer, which has proven to be our favourite upgrade.

For this equipment I simply use a rota and allocate a specific day to run either water production, laundry, ice making or water heating. We do laundry once a week without using the drying function and relying instead on nature’s outside dryer, which does tend to lower the tone of an idyllic anchorage.

The water maker produces 60 litres an hour and I typically run it for around four hours, which will then keep us going for several days. I fit in ice-making and heating the water at other times.

Having guests on board who insist on having a shower every time they go for a dip off the swimming platform requires the water maker to be run most days. Inevitably under these circumstances I lose the battle of consumption versus generation and will need to resort to running the generator.

We chose a Schenker Smart 60-litre-per-hour, 12V water maker rated at 20A, which enables free freshwater production all day long thanks to Spirit’s cluster of four solar panels.

I always delay this until my battery charge is showing 30 per cent or less in the morning. At that point I will run the generator for three to four hours, which is enough to get my batteries back up to around 70-80 per cent, and then let the solar panels take over.

When I run the generator, I take advantage of the surplus power it produces by running as many devices as possible: I make water, run the air-con and heat water. Never waste any of those precious amps! I find that I run the generator, on average, every eight to 10 days when we’re on our own and every four to five days when we have guests.

Batteries can be easily distributed around a yacht

Before increasing the capacity of your service battery bank you need to calculate your total power requirement by multiplying the amperage of all the equipment by the period of time it will be run over a charge cycle (usually 24hrs).

Tally up the amp hours and then double the result (to allow for not going below 50 per cent of your charge capacity). Then add another 20 per cent to ensure you will always have enough to spare.

If you already have separate engine start and service batteries but want to add further service batteries, they should all be of the same age, type and capacity (Ah rating) to the first. It’s best to create your service bank from a number of smaller batteries and then link them together to achieve the total voltage and capacity you require.

If you’re planning to install a large bank (500Ah or more), it is often better to use 6V cells for this as these allow a large deep-cycling bank to be created, while still having the ability to move them around easily or distribute them evenly over a greater area.

Create an improved service bank by connecting a number of smaller batteries

Stay in charge

Once you’ve decided on the battery type, make sure you have enough charging power to fully charge them between cycles. As a rough guide you will need to be able to bulk-charge the bank at a minimum of 10 per cent of its rated capacity (ie. 20A for a 200Ah battery).

However, 20 per cent is a better figure to aim for if you’re looking to fully recharge over one night in a marina. Modern AGM (absorbent glass mat) style batteries can usually take a greater charge than wet lead-acid type, although gel cells require a more particular regime if they are not to be damaged.

Chargers (both mains and alternator regulators) should be of the multi-stage type, with bulk, absorb and float stages. This allows the batteries to be rapidly charged until they reach around 90 per cent charge, then the charge voltage drops to attain the final part of the charge more slowly, keeping temperature (and hence internal resistance) down, and eliminating gassing.

A smart battery monitor will allow you see your state of charge and remaining capacity

Temperature noticeably affects a battery’s ability to give out and absorb charge. The colder a battery gets, the greater the power required to charge it fully. For this reason, always fit a charger or regulator with a temperature sensor that will automatically compensate for these differences.

Most power devices produce a trickle charge, and are used to keep the engine battery topped up. However, if you’re planning to install a powerful (5A+) wind or water generator, or a large solar array, then you’ll need to install some sort of voltage regulator to prevent overcharging. This can vary, from a small solid-state switch for small solar panels, to a large dump resistor that dissipates excess charge from a wind generator through heating up a wire-wound resistor.

Monitoring your batteries

The easiest way to ensure your batteries are kept in tip-top condition is to observe their state of charge every day you’re on board, using a modern ‘smart’ battery monitor. This will give you a real-time display of the current going in and out, the state of charge (SOC), and the remaining capacity available. They also often have alarms to warn you when the voltage is dropping dangerously low, or if too high a charge is being applied.

A rough idea of the SOC can be attained using a voltmeter, but this is not particularly accurate and can indicate a false condition when recently charged or under a heavy load. It’s far better to install a monitor that has a shunt, which measures current flow over time and can calculate the available charge capacity remaining much more precisely.

Hydrogenerators, like this Remoran Wave 3, will quickly recharge a yacht’s batteries underway

Optimising solar power

The efficiency of solar panels can be compromised by saltwater and long-term exposure to UV and high temperatures. Good regular maintenance will improve a solar panel’s performance.

Clean your solar panels early in the morning, while they are at their coolest, as cleaning them when they are warm or exposed to direct sunlight can cause internal thermal stresses.

Use distilled or deionized water to avoid the formation of mineral stains or deposits on the surface of the panels, and avoid using harsh chemicals or abrasive solvents that could scratch the photovoltaic cells. Let the panels air-dry or use soft cloths, and make sure no water residue is left. Check regularly for cracks, breaks or loose connections.

Hydrogenerators

Hydrogeneration has become a great deal more efficient in recent years. It’s a very simple concept: the yacht’s motion through the water turns an alternator on the transom-mounted hydrogenerator which generates electricity to recharge the boat’s batteries. Achieving 300Ah each day is a realistic expectation when cruising at 7-8 knots.

Oceanvolt’s High Power ServoProp 25 electric saildrive

Main prop regeneration

You can also use your main propeller to ‘regenerate’ electricity whilst under sail by using a parallel hybrid propulsion system where an electric motor is installed alongside the engine. Lynch Motors in Devon has supplied its systems to Vendée Globe boats for years, purely as a re-generator, and now produces a Red Snapper electric motor for cruising yachts.

The only problem with a regeneration system is that the pitch required for the propeller to drive the boat efficiently through the water may not always be the same as the pitch for optimum regeneration. Manufacturers have tackled this in different ways.

Oceanvolt has developed its ServoProp for saildrives, which electronically adjusts its pitch depending on speed and function. The latest incarnation allows total 360° blade mobility and faces forwards, increasing efficiency: at six knots, it produces an eye-watering 1kW of power.

Bruntons has another solution with the cleverly engineered Autoprop, which automatically pitches up to match the boat speed. Its Ecostar version of the prop can generate 200W at five knots and up to 1kW at 10 knots when connected to an electric motor.
