Hull Speed
The theoretical displacement-mode speed limit — determined by waterline length, not engine or sail power.
10.4 kts
A displacement hull pushes a bow wave whose speed is limited by the waterline length.
With a waterline of 60.3′, the Swan 65 Frers tops out around 10.4 knots in displacement mode — after that, the bow wave outruns the hull and resistance climbs steeply.
1.34 × √60.3′ LWL = 10.4 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
24.1%
Light ballast — tends to be tender; reef earlier than the numbers suggest.
Displacement / Length
122
Ultralight — responsive and fast, but carries less stores.
Hull Speed
10.4kts
Pounds/Inch Immersion
24lbs
Weight needed to sink the hull one inch — loading sensitivity.
