Hull Speed
The theoretical displacement-mode speed limit — determined by waterline length, not engine or sail power.
7.0 kts
A displacement hull pushes a bow wave whose speed is limited by the waterline length.
With a waterline of 27.0′, the Swift 33 tops out around 7.0 knots in displacement mode — after that, the bow wave outruns the hull and resistance climbs steeply.
1.34 × √27.0′ LWL = 7.0 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
35.8%
Typical cruising ballast — balanced stability and motion underway.
Displacement / Length
334
Moderate-heavy — carries provisions well, deliberate in light air.
Hull Speed
7.0kts
Pounds/Inch Immersion
7lbs
Weight needed to sink the hull one inch — loading sensitivity.
