Performance Ratios

On the numbers, 517 rates as high-powered (SA/D 24.1) and ultralight (D/L 100). Its comfort ratio of 7.0 is in the "lightweight racing" band; its capsize screening value of 2.64 is in the "above the guideline" band.

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

Hull Speed: 5.23 knots

SA/Displacement (Calc): 24.05

SA/D 24.1 — high-powered. Higher than 59% of the 86 monohulls between 4.6 m and 5.8 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): 24.11

Displacement/Length: 99.75

D/L 100 — ultralight. Lower than 58% of the 403 monohulls between 4.6 m and 5.8 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: 7.00

Comfort ratio 7.0 — lightweight racing. Lower than 54% of the 403 monohulls between 4.6 m and 5.8 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: 2.64

Capsize screening 2.64 — above the guideline. Lower than 64% of the 512 monohulls between 4.6 m and 5.8 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: 5.36

S-number 5.4. Higher than 67% of the 82 monohulls between 4.6 m and 5.8 m in our catalogue. A stability number combining hull form and ballast: higher values indicate better stability and sea-keeping.

Immersion: 59 kg/cm
