Performance Ratios

On the numbers, 11 Meter rates as high-powered (SA/D 28.4) and ultralight (D/L 81). Its comfort ratio of 11.4 is in the "lightweight racing" band; its ballast/displacement ratio of 45.3% is in the "high" band. Against its peers, D/L stands out: lower than 99% of the 1906 monohulls between 9.3 m and 11.3 m in our catalogue.

Ratios use published displacement (often light ship) and reported sail area; see Sources & methodology.

Hull Speed: 6.95 knots

SA/Displacement (Calc): 28.36

SA/D 28.4 — high-powered. Higher than 98% of the 1252 monohulls between 9.3 m and 11.3 m in our catalogue. Sail area relative to displacement: the higher the number, the more sail the boat carries for its weight, which means more power in light air.

SA/Displacement (Reported): 31.16

Ballast/Disp Ratio: 45.31%

Ballast/Disp 45.3% — high. Higher than 82% of the 1723 monohulls between 9.3 m and 11.3 m in our catalogue. The share of the boat's weight that is ballast: a higher share generally means a stiffer boat that stands up better to its sail area.

Displacement/Length: 80.89

D/L 81 — ultralight. Lower than 99% of the 1906 monohulls between 9.3 m and 11.3 m in our catalogue. Displacement relative to waterline length: low numbers mean a light boat that accelerates and planes easily, high numbers a heavy boat that carries its weight through a seaway.

Comfort Ratio: 11.41

Comfort ratio 11.4 — lightweight racing. Lower than 99% of the 1905 monohulls between 9.3 m and 11.3 m in our catalogue. An estimate of motion comfort in waves from displacement, beam and length: higher values suggest a slower, gentler motion.

Capsize Screening: 2.16

Capsize screening 2.16 — above the guideline. Higher than 88% of the 1942 monohulls between 9.3 m and 11.3 m in our catalogue. A screening formula from beam and displacement: lower is better, and values under 2.0 are the common guideline for offshore boats.

S-Number: 6.48

S-number 6.5. Higher than 98% of the 1233 monohulls between 9.3 m and 11.3 m in our catalogue. A stability number combining hull form and ballast: higher values indicate better stability and sea-keeping.

Immersion: 141 kg/cm
