Hull Speed
The theoretical displacement-mode speed limit — determined by waterline length, not engine or sail power.
7.9 kts
A displacement hull pushes a bow wave whose speed is limited by the waterline length.
With a waterline of 34.3′, the Worldcruiser 50 tops out around 7.9 knots in displacement mode — after that, the bow wave outruns the hull and resistance climbs steeply.
1.34 × √34.3′ LWL = 7.9 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
40.6%
Stiff enough to carry a big genoa comfortably into moderate breeze.
Displacement / Length
353
Heavy displacement — a slow, steady, seakindly hull.
Hull Speed
7.9kts
Pounds/Inch Immersion
10lbs
Weight needed to sink the hull one inch — loading sensitivity.
