Hull Speed
The theoretical displacement-mode speed limit — determined by waterline length, not engine or sail power.
5.8 kts
A displacement hull pushes a bow wave whose speed is limited by the waterline length.
With a waterline of 18.5′, the Venture 21 tops out around 5.8 knots in displacement mode — after that, the bow wave outruns the hull and resistance climbs steeply.
1.34 × √18.5′ LWL = 5.8 kts
Performance Ratios
Racing handicap, sail-carrying power, stability and comfort — and what each one actually tells you about a day on the water.
PHRF Rating
252s/nm
Heavy or slow cruiser — all about the journey, not the elapsed time.
Ballast / Displacement
26.7%
Light ballast — tends to be tender; reef earlier than the numbers suggest.
Displacement / Length
106
Ultralight — responsive and fast, but carries less stores.
Hull Speed
5.8kts
Pounds/Inch Immersion
3lbs
Weight needed to sink the hull one inch — loading sensitivity.
