Hull Speed
The theoretical displacement-mode speed limit — determined by waterline length, not engine or sail power.
5.6 kts
A displacement hull pushes a bow wave whose speed is limited by the waterline length.
With a waterline of 17.7′, the Varianta tops out around 5.6 knots in displacement mode — after that, the bow wave outruns the hull and resistance climbs steeply.
1.34 × √17.7′ LWL = 5.6 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
44.1%
Stiff enough to carry a big genoa comfortably into moderate breeze.
Displacement / Length
104
Ultralight — responsive and fast, but carries less stores.
Hull Speed
5.6kts
Pounds/Inch Immersion
3lbs
Weight needed to sink the hull one inch — loading sensitivity.
