Hull Speed
The theoretical displacement-mode speed limit — determined by waterline length, not engine or sail power.
6.0 kts
A displacement hull pushes a bow wave whose speed is limited by the waterline length.
With a waterline of 20.0′, the Tomahawk 25 tops out around 6.0 knots in displacement mode — after that, the bow wave outruns the hull and resistance climbs steeply.
1.34 × √20.0′ LWL = 6.0 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
43.4%
Stiff enough to carry a big genoa comfortably into moderate breeze.
Displacement / Length
283
Moderate-heavy — carries provisions well, deliberate in light air.
Hull Speed
6.0kts
Pounds/Inch Immersion
4lbs
Weight needed to sink the hull one inch — loading sensitivity.
