About the Astus 201

With limited specifications available, the Astus 201 represents an intriguing entry in the world of performance multihulls. This trimaran design emerges from the French boat-building tradition that has consistently pushed boundaries in multihull sailing, following the legacy established by other innovative designs in the Astus line. Built for sailors seeking the exhilarating performance characteristics that only a trimaran can deliver, this boat excels in coastal sailing and day sailing scenarios where speed and responsiveness take priority. The trimaran configuration provides exceptional stability and reduced heeling compared to monohulls, making it particularly appealing to sailors transitioning from traditional single-hull designs. Notable for its lightweight construction and sleek profile, the Astus 201 delivers impressive sailing performance while maintaining manageable handling characteristics. The design philosophy emphasizes speed without sacrificing control, making it suitable for both recreational sailing and competitive racing applications. Its French engineering heritage suggests attention to detail in hydrodynamics and sail handling systems. For sailors prioritizing performance and seeking the unique sailing experience that only a well-designed trimaran can provide, the Astus 201 offers an compelling option in the performance multihull market, though prospective buyers should seek detailed specifications to fully evaluate its capabilities.

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
52.94
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
2.23
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
5.41
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. 5.87 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. 5.23 pounds/inch
Rig Dimensions
I (Foretriangle Height) 1.15 ft / 0.35 m
P (Mainsail Luff) 322.90 ft² / 30.00 m²
E (Mainsail Foot) 52.94
