About the Sun Fast 43 Jeanneau

Part of Jeanneau's acclaimed Sun Fast range, this 43-footer represents the French builder's commitment to creating versatile performance cruisers that excel in both racing and cruising applications. The Sun Fast line has earned recognition for bridging the gap between pure racing machines and comfortable cruising yachts, making serious sailing accessible to a broader range of sailors. Built with racing-inspired hull lines and optimized weight distribution, the Sun Fast 43 delivers impressive performance while maintaining the creature comforts expected in a modern cruising yacht. The design emphasizes ease of handling, allowing couples or small crews to manage the boat confidently in various conditions. Its moderate displacement and efficient sail plan make it well-suited for coastal cruising, offshore passages, and club racing. Jeanneau's reputation for solid construction and thoughtful interior layouts shines through in this model. The cockpit design prioritizes both sailing efficiency and social comfort, while below decks, the accommodation plan balances privacy with open living spaces. This combination of performance, comfort, and manageable size makes the Sun Fast 43 an attractive option for sailors seeking one boat that can handle weekend getaways, longer cruises, and competitive sailing with equal competence.

Performance Ratios
SA/Displacement Sail Area to Displacement ratio measures how much sail power a boat has relative to its weight. Higher values mean more performance and speed.
Under 14 — Heavy cruiser, slow14–18 — Cruising sailboat18–22 — Cruiser/racerOver 22 — Performance racer
23.31
Ballast/Displacement Ballast to Displacement ratio shows what percentage of the boat's total weight is ballast. Higher values generally mean better initial stability and stiffer sail carrying.
30–35% — Typical cruiser35–45% — Stiff performance boatOver 45% — Racing oriented
40.0
Displacement/Length Displacement to Length ratio measures how heavy a boat is relative to its waterline length. Lower values mean a lighter, faster boat.
Under 100 — Ultralight racer100–200 — Light cruiser/racer200–300 — Moderate cruiser300–400 — Heavy cruiserOver 400 — Very heavy
146.59
Comfort Ratio Ted Brewer's Comfort Ratio predicts how comfortable a boat will feel in offshore conditions. Higher values mean a steadier, more comfortable motion in a seaway.
Under 20 — Uncomfortably rough20–30 — Acceptable coastal30–40 — Good offshore comfortOver 40 — Very comfortable offshore
20.76
Capsize Screening Formula The USHS Capsize Screening Formula estimates offshore capsize risk. Lower is safer — values under 2.0 are considered acceptable for offshore sailing.
Under 2.0 — Safe for offshore2.0–2.2 — Borderline offshoreOver 2.2 — Coastal use recommended
2.12
Hull Speed Hull Speed is the theoretical maximum speed of a displacement hull, calculated from waterline length. Most cruising sailboats reach this speed in moderate conditions. 8.23 kn
Pounds/Inch Immersion Pounds per Inch Immersion (PPI) tells you how much weight is needed to sink the boat one inch. Useful for calculating how additional gear and stores affect waterline. 11.14 pounds/inch
