About the Buccaneer 36 Crowther

Lock Crowther's Buccaneer 36 represents a pioneering era in multihull design, when performance-oriented trimarans began gaining recognition among serious sailors. First introduced in 1974, this 35.75-foot trimaran showcases Crowther's renowned expertise in creating fast, seaworthy multihulls that blur the line between racing and cruising applications. The design's impressive 26-foot beam provides exceptional stability and spacious accommodations, while the relatively light 7,100-pound displacement contributes to spirited performance under the masthead sloop rig. With 821 square feet of sail area and a sail area-to-displacement ratio of 35.67, the Buccaneer 36 delivers the exhilarating speed potential that draws sailors to multihull sailing. Built from either fiberglass or plywood construction methods, these boats were primarily constructed by various builders working from Crowther's proven plans, making each example somewhat unique while maintaining the designer's core performance characteristics. The trimaran configuration with daggerboards offers excellent upwind ability and shallow-draft versatility for exploring varied cruising grounds. This design appeals particularly to sailors seeking coastal and offshore cruising capability combined with the excitement of multihull performance, representing solid value in the growing vintage multihull market.

Performance Ratios
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
4.2
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
