Design ratios

Computed from the specs above using the standard formulas. Try the sailboat calculators with your own numbers.

SA / Displacement 21.50 Performance / racer — powered up
Ballast / Displacement 39.3 % Higher = stiffer / more sail-carrying power
Displacement / Length 142 Light
Comfort Ratio 11.6 Racing / light coastal
Capsize Screening 2.41 Better suited to coastal use (> 2.0)
Hull Speed 6.1 kn Theoretical max displacement speed
How these numbers are calculated
SA / Displacement
SA ÷ (Disp ÷ 64)^(2/3) — Power-to-weight. < 16 under-canvassed, 16–20 cruiser, > 20 racer.
Ballast / Displacement
Ballast ÷ Disp × 100 — Stability/stiffness. Higher carries sail better.
Displacement / Length
Disp(lt) ÷ (0.01 · LWL)³ — < 100 ultralight, 100–200 light, 200–300 moderate, > 300 heavy.
Comfort Ratio (Brewer)
Disp ÷ (0.65 · (0.7·LWL + 0.3·LOA) · Beam^1.33) — Motion in a seaway. Higher = more comfortable offshore.
Capsize Screening
Beam ÷ (Disp ÷ 64)^(1/3) — ≤ 2.0 favored for offshore; > 2.0 better for coastal use.
Hull Speed
1.34 · √LWL — Theoretical max displacement speed in knots.
