The Aqua Finn is aggressively canvassed for its weight.
Performance Ratios
Racing handicap, sail-carrying power, stability and comfort — and what each one actually tells you about a day on the water.
SA / Displacement
46.8
Performance-oriented — carries a lot of canvas for its weight.
Capsize Screening
3.29
Above the 2.0 offshore threshold — best suited for coastal and protected waters.
Motion & Offshore Suitability
Two ratios that matter most when you're planning passages — how the boat feels in a seaway, and whether the hull geometry is suitable for open ocean.
Capsize Screening Formula
3.29
Above the 2.0 offshore threshold — best suited for coastal and protected waters.
Under 2.0 — Acceptable for offshore
Over 2.0 — Coastal / protected waters
Wind Range & Comfort Envelope
Estimated wind ranges for comfortable sailing on the Aqua Finn — based on sail area, ballast, and displacement characteristics.
Ghosting
0–5 kts
Light air, motor-sailing likely. Need patience and a light genoa.
Sweet Spot
5–16 kts
Comfortable under full sail. Best speed-to-comfort ratio.
Time to Reef
16–24 kts
Time to shorten sail. Reef the main, swap to a working jib.
Heavy Weather
24+ kts
Storm conditions. Storm jib or bare poles. Seek shelter if coastal.
