Hull Speed
The theoretical displacement-mode speed limit — determined by waterline length, not engine or sail power.
6.1 kts
A displacement hull pushes a bow wave whose speed is limited by the waterline length.
With a waterline of 21.0′, the Seamew 22 tops out around 6.1 knots in displacement mode — after that, the bow wave outruns the hull and resistance climbs steeply.
1.34 × √21.0′ LWL = 6.1 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
16.1%
Light ballast — tends to be tender; reef earlier than the numbers suggest.
Displacement / Length
149
Ultralight — responsive and fast, but carries less stores.
Hull Speed
6.1kts
Pounds/Inch Immersion
3lbs
Weight needed to sink the hull one inch — loading sensitivity.
