The Sun Odyssey 45.2 Jeanneau is with acceptable motion comfort for coastal passages.
Hull Speed
The theoretical displacement-mode speed limit — determined by waterline length, not engine or sail power.
8.3 kts
A displacement hull pushes a bow wave whose speed is limited by the waterline length.
With a waterline of 38.4′, the Sun Odyssey 45.2 Jeanneau tops out around 8.3 knots in displacement mode — after that, the bow wave outruns the hull and resistance climbs steeply.
1.34 × √38.4′ LWL = 8.3 kts
Performance Ratios
Racing handicap, sail-carrying power, stability and comfort — and what each one actually tells you about a day on the water.
Ballast / Displacement
34.0%
Typical cruising ballast — balanced stability and motion underway.
Displacement / Length
165
Moderate — a good balance of speed and load-carrying ability.
Comfort Ratio
22.0
Acceptable coastal comfort — fine for weekends, notice the chop offshore.
Capsize Screening
2.14
Above the 2.0 offshore threshold — best suited for coastal and protected waters.
Hull Speed
8.3kts
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
22.0
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
2.14
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
