Hull Speed
The theoretical displacement-mode speed limit — determined by waterline length, not engine or sail power.
7.6 kts
A displacement hull pushes a bow wave whose speed is limited by the waterline length.
With a waterline of 31.8′, the Ocean 40 Mull tops out around 7.6 knots in displacement mode — after that, the bow wave outruns the hull and resistance climbs steeply.
1.34 × √31.8′ LWL = 7.6 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
47.9%
Race-oriented ballast ratio — very stiff and powerful.
Displacement / Length
263
Moderate-heavy — carries provisions well, deliberate in light air.
Hull Speed
7.6kts
Pounds/Inch Immersion
9lbs
Weight needed to sink the hull one inch — loading sensitivity.
