The Blue Djinn is well-powered with enough sail area to move in light air.
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
21.9
Powerful cruiser/racer — quick in light air, reef early when it pipes up.
Ballast / Displacement
16.7%
Light ballast — tends to be tender; reef earlier than the numbers suggest.
Capsize Screening
2.48
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
2.48
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 Blue Djinn — based on sail area, ballast, and displacement characteristics.

0–6 kts
Light air, motor-sailing likely. Need patience and a light genoa.
Sweet Spot
6–16 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.
