The Sun Odyssey 44I Perf Jeanneau is aggressively canvassed for its weight, with acceptable motion comfort for coastal passages.
Hull Speed
The theoretical displacement-mode speed limit — determined by waterline length, not engine or sail power.
A displacement hull pushes a bow wave whose speed is limited by the waterline length.
With a waterline of 37.6′, the Sun Odyssey 44I Perf Jeanneau tops out around 8.2 knots in displacement mode — after that, the bow wave outruns the hull and resistance climbs steeply.
1.34 × √37.6′ LWL = 8.2 kts
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
23.0
Performance-oriented — carries a lot of canvas for its weight.
Ballast / Displacement
28.9%
Light ballast — tends to be tender; reef earlier than the numbers suggest.
Displacement / Length
184
Moderate — a good balance of speed and load-carrying ability.
Comfort Ratio
24.5
Acceptable coastal comfort — fine for weekends, notice the chop offshore.
Capsize Screening
2.05
Above the 2.0 offshore threshold — best suited for coastal and protected waters.
SA/Disp (Calculated)
18.4
Computed from measured I/J/P/E rather than reported sail area.
Pounds/Inch Immersion
1lbs
Weight needed to sink the hull one inch — loading sensitivity.
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.
Comfort Ratio
24.5
Acceptable coastal comfort — fine for weekends, notice the chop offshore.
Under 20 — Snappy, racing motion
20–30 — Acceptable coastal
30–40 — Good offshore comfort
Over 40 — Very comfortable offshore
Capsize Screening Formula
2.05
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

These are simplified estimates based on hull speed (8.2 kts),
SA/D (23.0), and empirical efficiency curves — not instrument-measured
polars. Real-world speed varies with sea state, bottom condition, sail trim, and current.
Speeds in gold approach hull speed;
bold gold means near or at hull speed.
Wind Range & Comfort Envelope

Heavy
0–5 kts

Ghosting
0–5 kts
Light air, motor-sailing likely. Need patience and a light genoa.
Sweet Spot
5–14 kts
Comfortable under full sail. Best speed-to-comfort ratio.
Time to Reef
14–22 kts
Time to shorten sail. Reef the main, swap to a working jib.
Heavy Weather
22+ kts
Storm conditions. Storm jib or bare poles. Seek shelter if coastal.
