About the Py 90

Built by Proteus Yachts beginning in 1999, this Felci-designed 30-footer represents a compelling blend of performance and practicality for coastal cruising and club racing. The Py 90's fractional sloop rig and moderate displacement of 4,960 pounds create a responsive platform that rewards active sailing while maintaining reasonable comfort for weekend getaways. The hull configuration features a modern fin keel with bulb and spade rudder arrangement, delivering crisp handling characteristics that make the boat particularly engaging in moderate conditions. With a sail area to displacement ratio of 30.12, the design strikes a nice balance between spirited performance and manageable power, making it accessible to crews of varying experience levels. At just under 30 feet overall with a 10.5-foot beam, the Py 90 offers a practical size for trailer sailing while providing enough interior volume for comfortable short-term cruising. The fiberglass construction ensures durability and relatively low maintenance requirements. The capsize screening formula of 2.47 indicates good stability characteristics suitable for coastal waters, though the design is best appreciated in protected to semi-protected sailing areas where its performance-oriented nature can truly shine. This makes it an excellent choice for sailors seeking an engaging boat that can handle both spirited day sailing and comfortable overnight adventures.

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
140.02
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
12.57
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. 6.71 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. 5.65 pounds/inch
