About the Etap 48Ds

Belgian builder Etap Yachting introduced the 48Ds in 2009 as a sophisticated bluewater cruiser, combining their renowned unsinkable hull technology with elegant Italian styling from Stile Bertone and naval architecture by Von Ahlen Yacht Design. This 47-foot fractional sloop represents Etap's commitment to safe, comfortable offshore sailing with distinctive design flair. The 48Ds features Etap's signature foam-filled hull construction, making it virtually unsinkable—a compelling safety feature for serious cruisers venturing beyond coastal waters. With a displacement of over 29,000 pounds and substantial ballast, this yacht offers the stability and seakindness expected of a proper offshore cruiser. The wing keel configuration provides good upwind performance while reducing draft to 6.73 feet, opening up more shallow anchorages. Her moderate sail-area-to-displacement ratio of 14.25 and comfortable 29.06 comfort ratio indicate a yacht optimized for relaxed passage making rather than racing. The low capsize screening value of 1.92 confirms her offshore capabilities. With nearly 840 square feet of sail area and a hull speed approaching 8.6 knots, the 48Ds delivers respectable performance while prioritizing comfort and safety for extended cruising adventures.

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
14.25
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
31.82
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
188.36
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
29.06
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
1.92
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
S# (Speed Number) The Speed Number (S#) is a quick performance index. Higher values indicate a faster, more powerful design relative to its size.
Under 3.0 — Slow cruiser3.0–5.0 — Average cruiser5.0–7.0 — Performance cruiserOver 7.0 — Racer
2.62
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. 2,162.83 pounds/inch
SA/Displacement (Calc) Calculated Sail Area to Displacement ratio using actual measured sail dimensions rather than reported values. More precise than the reported SA/Disp figure. 15.25
