About the Cr 310

Swedish designer Håkan Södergren created this well-balanced 31-footer for CR Yachts during an eleven-year production run from 1997 to 2008. The CR 310 exemplifies Scandinavian design philosophy with its moderate proportions and emphasis on seaworthiness over pure performance. Built with GRP construction and featuring a fin keel with rudder on partial skeg configuration, this fractional sloop offers predictable handling characteristics that appeal to both coastal cruisers and sailors venturing offshore. The boat's 25.02 comfort ratio indicates generous interior volume relative to its size, while the conservative 1.88 capsize screening value reflects inherent stability suitable for extended cruising. With 520.97 square feet of sail area driving 9,259 pounds of displacement, the CR 310 delivers respectable performance without sacrificing comfort. The substantial ballast-to-displacement ratio provides confidence-inspiring stability in challenging conditions. The partial skeg design protects the rudder while maintaining good directional control. This yacht suits sailors seeking a capable coastal cruiser with offshore potential. The moderate beam and draft make marina access straightforward, while the robust Scandinavian build quality ensures longevity. Whether exploring archipelagos or undertaking longer passages, the CR 310 offers a practical blend of comfort, safety, and sailing performance.

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
18.97
Ballast/Displacement Ballast to Displacement ratio shows what percentage of the boat's total weight is ballast. Higher values generally mean better initial stability and stiffer sail carrying.
30–35% — Typical cruiser35–45% — Stiff performance boatOver 45% — Racing oriented
41.67
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
246.67
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
25.02
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
1.88
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. 6.78 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. 899.73 pounds/inch
