Performance Ratios

On the numbers, 510 (Lanaverre) rates as ultralight (D/L 92). Its comfort ratio of 6.8 is in the "lightweight racing" band; its ballast/displacement ratio of 22.5% is in the "low" band. Against its peers, Ballast/Disp stands out: lower than 81% of the 264 monohulls between 4.6 m and 5.8 m in our catalogue.

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

Hull Speed: 5.29 knots

SA/Displacement (Reported): 23.58

Ballast/Disp Ratio: 22.48%

Ballast/Disp 22.5% — low. Lower than 81% of the 264 monohulls between 4.6 m and 5.8 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: 92.43

D/L 92 — ultralight. Lower than 60% 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: 6.81

Comfort ratio 6.8 — lightweight racing. Lower than 56% 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: 2.65

Capsize screening 2.65 — above the guideline. Lower than 63% 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.
