Hull Speed
The theoretical displacement-mode speed limit — determined by waterline length, not engine or sail power.
7.3 kts
A displacement hull pushes a bow wave whose speed is limited by the waterline length.
With a waterline of 29.5′, the F 36 tops out around 7.3 knots in displacement mode — after that, the bow wave outruns the hull and resistance climbs steeply.
1.34 × √29.5′ LWL = 7.3 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
52.3%
Race-oriented ballast ratio — very stiff and powerful.
Displacement / Length
190
Moderate — a good balance of speed and load-carrying ability.
Hull Speed
7.3kts
Pounds/Inch Immersion
8lbs
Weight needed to sink the hull one inch — loading sensitivity.
