Performance Ratios

On the numbers, FAMILY CAT 23 rates as heavy (D/L 300). Its comfort ratio of 20.2 is in the "coastal cruiser" band; its ballast/displacement ratio of 23.3% is in the "low" band. Against its peers, Ballast/Disp stands out: lower than 95% of the 979 monohulls between 6.3 m and 7.7 m in our catalogue.

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

Hull Speed: 6.10 knots

SA/Displacement (Reported): 20.12

Ballast/Disp Ratio: 23.33%

Ballast/Disp 23.3% — low. Lower than 95% of the 979 monohulls between 6.3 m and 7.7 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: 299.81

D/L 300 — heavy. Higher than 89% of the 1066 monohulls between 6.3 m and 7.7 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: 20.15

Comfort ratio 20.2 — coastal cruiser. Higher than 85% of the 1066 monohulls between 6.3 m and 7.7 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: 2.20

Capsize screening 2.20 — above the guideline. Lower than 54% of the 1129 monohulls between 6.3 m and 7.7 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: 132 kg/cm
