About the Astus 14 5

French design expertise meets modern trimaran innovation in this compact multihull from VPLP Design and Astus Boats. Launched in 2020, this 14.27-foot trimaran represents a fascinating entry point into multihull sailing, combining the stability and speed advantages of three hulls with remarkably light displacement at just 85.98 pounds. The boat's proportions tell an interesting story—its generous 7.87-foot beam provides exceptional stability for coastal sailing and day trips, while the 2.30-foot draft keeps shallow waters accessible. The masthead sloop rig delivers 107.64 square feet of sail area, creating an impressive sail area-to-displacement ratio of 88.43 that promises spirited performance in light to moderate conditions. VPLP Design, renowned for their America's Cup and offshore racing multihulls, brings serious pedigree to this compact platform. The fiberglass construction ensures durability while maintaining the light weight essential for car-top transport and single-handed launching. This design particularly appeals to sailors seeking an introduction to multihull sailing or those wanting a high-performance daysailer that can be easily transported and rigged. The trimaran configuration offers forgiveness compared to catamarans while delivering the speed and excitement that makes multihull sailing addictive.

Performance Ratios
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
21.51
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
0.66
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
7.13
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. 4.67 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. 2.05 pounds/inch
