About the Etap 46Ds

Belgian builder Etap Yachting produced this distinctive 47-footer from 2006 to 2009, collaborating with Von Ahlen Yacht Design on the hull and the renowned Stile Bertone design house for the interior styling. The 46Ds represents Etap's commitment to innovative construction techniques, featuring their signature unsinkable foam-cored fiberglass hull design that eliminates the need for traditional through-hull fittings below the waterline. With a moderate displacement of 28,329 pounds and generous beam of 14.44 feet, this fractional sloop strikes an appealing balance between performance and comfort. The tandem keel configuration provides excellent stability while maintaining a reasonable 5.09-foot draft for accessing shallow anchorages. Her sail area-to-displacement ratio of 19.32 indicates spirited sailing performance without being overly aggressive, making her well-suited for both coastal cruising and offshore passages. The comfort ratio of 29.12 suggests a boat designed more for performance-oriented cruising than heavy displacement voyaging, while the capsize screening value of 1.9 falls within acceptable limits for ocean sailing. The collaboration with Stile Bertone, famous for automotive design, brought distinctive Italian flair to the interior spaces, setting this model apart from typical production cruisers of the era.

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
19.32
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
32.68
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
183.36
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
29.12
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
1.9
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. 8.58 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. 2,115.94 pounds/inch
