Dufour Atoll 43
Dufour Atoll 43 is a 43 ′ 0 ″ / 13.1 m monohull sailboat designed by Philippe Briand and built by Dufour Yachts starting in 1998.
Rig and Sails
Auxilary power, accomodations, calculations.
The theoretical maximum speed that a displacement hull can move efficiently through the water is determined by it's waterline length and displacement. It may be unable to reach this speed if the boat is underpowered or heavily loaded, though it may exceed this speed given enough power. Read more.
Classic hull speed formula:
Hull Speed = 1.34 x √LWL
Max Speed/Length ratio = 8.26 ÷ Displacement/Length ratio .311 Hull Speed = Max Speed/Length ratio x √LWL
Sail Area / Displacement Ratio
A measure of the power of the sails relative to the weight of the boat. The higher the number, the higher the performance, but the harder the boat will be to handle. This ratio is a "non-dimensional" value that facilitates comparisons between boats of different types and sizes. Read more.
SA/D = SA ÷ (D ÷ 64) 2/3
- SA : Sail area in square feet, derived by adding the mainsail area to 100% of the foretriangle area (the lateral area above the deck between the mast and the forestay).
- D : Displacement in pounds.
Ballast / Displacement Ratio
A measure of the stability of a boat's hull that suggests how well a monohull will stand up to its sails. The ballast displacement ratio indicates how much of the weight of a boat is placed for maximum stability against capsizing and is an indicator of stiffness and resistance to capsize.
Ballast / Displacement * 100
Displacement / Length Ratio
A measure of the weight of the boat relative to it's length at the waterline. The higher a boat’s D/L ratio, the more easily it will carry a load and the more comfortable its motion will be. The lower a boat's ratio is, the less power it takes to drive the boat to its nominal hull speed or beyond. Read more.
D/L = (D ÷ 2240) ÷ (0.01 x LWL)³
- D: Displacement of the boat in pounds.
- LWL: Waterline length in feet
Comfort Ratio
This ratio assess how quickly and abruptly a boat’s hull reacts to waves in a significant seaway, these being the elements of a boat’s motion most likely to cause seasickness. Read more.
Comfort ratio = D ÷ (.65 x (.7 LWL + .3 LOA) x Beam 1.33 )
- D: Displacement of the boat in pounds
- LOA: Length overall in feet
- Beam: Width of boat at the widest point in feet
Capsize Screening Formula
This formula attempts to indicate whether a given boat might be too wide and light to readily right itself after being overturned in extreme conditions. Read more.
CSV = Beam ÷ ³√(D / 64)
Intended specifically for the charter trade. Cabins: 3/4 3/4 Heads/Showers: 2 2 Head Room: 6.25’

Dufour Atoll 43
Described as the "inside-out boat", the atoll 43 has been specifically designed for charter use, with all the main living and entertaining areas located up on deck around the cockpit.
According to the Australian importer Karen Maxwell, the Atoll's party platform concept is ideal for cruising and entertaining, particularly in warmer climes.
The exterior living space offers panoramic views and takes up close to half the boat's 13.0m length. Indicative of its role as a comfortable cruiser, the vessel has a generous 4.64m beam.
The daytime area, above deck, features a large saloon with padded wraparound seating, a vast galley to port with more than 300lt cold storage and a navigation station to starboard. The living space is sheltered from the elements with a hard top, hood and windscreen. The area can be heated if necessary.
Another unusual creature comfort is the cushioned sunbathing well set into the foredeck. At the walk-through transom is a well and swim ladder to provide easy access into the cockpit.
Three steps lead under the deck, which has been designed on simple and functional lines. Accommodating a charter party of up to eight, it has four double berths with the two front cabins transforming into one master if required. There are opening hatches and ports in all the cabins for good ventilation, purpose-built lockers and ample stowage space throughout.
Despite its cruising credentials, sailability has not been ignored, Maxwell says. The Atoll range, which now includes 36 and 50-foot versions, is designed by Phillipe Briand, known for a number of successful French racing yachts. It has a large fractional rig with fully-battened mainsail, single line reefing and a furling headsail with just 110% overlap, making it easy to handle. Set up for single-handed sailing, all the winches, sheets and control lines are positioned within easy reach of the helmsman.
When powered by a 62hp motor with three-bladed prop, the Atoll 43 can reach speeds of up to 8kt.
Providing true bluewater cruising autonomy, the vessel is equipped with twin 550lt water tanks and carries 500lt of fuel.

Designed to determine if a boat has blue water capability. The CSF compares beam with displacement since excess beam contributes to capsize and heavy displacement reduces capsize vulnerability. The boat is better suited for ocean passages (vs coastal cruising) if the result of the calculation is 2.0 or less. The lower the better.
The Dufour Atoll 43 is a monohull offering the space of a catamaran. This surprising "monomaran" with a huge cockpit has a spacious saloon and kitchen. A roomy interior of 4 cabins and 2 heads allows you to invite some more guests.
