About the Etap 34S

Belgian builder Etap Yachting produced this well-regarded cruising sailboat from 1997 to 2006, with 85 hulls completing the production run. Designed by the Mortain & Mavrikios team, the 34S represents solid European craftsmanship in fiberglass construction, measuring just under 35 feet overall with a nearly 30-foot waterline. The fractional sloop rig and fin keel configuration deliver respectable sailing performance, with a sail area to displacement ratio of 23.52 indicating good light-air capability without sacrificing stability. The generous beam of 11.55 feet provides spacious accommodations below while maintaining seaworthily proportions. A displacement of 10,000 pounds with 3,200 pounds of ballast creates a stable platform suitable for coastal cruising and short offshore passages. The comfort ratio of 18.98 suggests motion characteristics favoring cruising over racing, while the capsize screening formula of 2.15 indicates reasonable offshore capability when properly handled. Hull speed potential reaches 7.31 knots under ideal conditions. Etap's reputation for solid construction and practical layouts makes the 34S an attractive option for sailors seeking a capable European cruiser with proven seakeeping qualities and comfortable accommodations for extended voyaging.

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
 23.52
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
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
 169.38
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
 18.98
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
 2.15
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. 7.31 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. 1,228.18 pounds/inch
