About the Gp 26 Orc

Designed as a competitive one-design racing sailboat, this 26-foot performance-oriented vessel represents modern racing yacht design principles scaled down to a manageable size. The Gp 26 Orc features a sophisticated hull configuration with a fin keel and bulb combination paired with a spade rudder, delivering the kind of efficiency and responsiveness that serious racers demand. With its fractional sloop rig and generous sail area to displacement ratio of 33.04, this boat excels in competitive sailing scenarios where speed and agility are paramount. The composite construction follows strict rule specifications, ensuring fair competition while maintaining the structural integrity needed for spirited racing conditions. The substantial ballast ratio provides impressive stability, allowing crews to carry sail effectively in a wide range of wind conditions. First launched in 2013, the design has been built by various manufacturers, reflecting its appeal within the racing community. The capsize screening formula of 2.6 indicates this is primarily suited for protected waters and coastal racing rather than extended offshore passages. The boat's relatively deep draft and performance-focused design make it ideal for yacht club racing, regatta competition, and sailors who prioritize speed and handling precision over cruising comfort or shallow-water accessibility.

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
33.04
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
92.04
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
8.49
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. 6.29 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. 3.99 pounds/inch
SA/Displacement (Calc) Calculated Sail Area to Displacement ratio using actual measured sail dimensions rather than reported values. More precise than the reported SA/Disp figure. 33.08
