Hull Speed
The theoretical displacement-mode speed limit — determined by waterline length, not engine or sail power.
10.0 kts
A displacement hull pushes a bow wave whose speed is limited by the waterline length.
With a waterline of 56.1′, the Swan 58 tops out around 10.0 knots in displacement mode — after that, the bow wave outruns the hull and resistance climbs steeply.
1.34 × √56.1′ LWL = 10.0 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
29.5%
Light ballast — tends to be tender; reef earlier than the numbers suggest.
Displacement / Length
142
Ultralight — responsive and fast, but carries less stores.
Hull Speed
10.0kts
Pounds/Inch Immersion
21lbs
Weight needed to sink the hull one inch — loading sensitivity.
