Performance Ratios

On the numbers, 490 rates as ultralight (D/L 39). Its comfort ratio of 2.8 is in the "lightweight racing" band; its capsize screening value of 3.49 is in the "above the guideline" band. Against its peers, D/L stands out: lower than 87% of the 373 monohulls between 4.3 m and 5.5 m in our catalogue.

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

Hull Speed: 5.14 knots

SA/Displacement (Reported): 58.00

Displacement/Length: 39.35

D/L 39 — ultralight. Lower than 87% of the 373 monohulls between 4.3 m and 5.5 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: 2.82

Comfort ratio 2.8 — lightweight racing. Lower than 87% of the 373 monohulls between 4.3 m and 5.5 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: 3.49

Capsize screening 3.49 — above the guideline. Higher than 77% of the 504 monohulls between 4.3 m and 5.5 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.

Immersion: 53 kg/cm
