Hull Speed
The theoretical displacement-mode speed limit — determined by waterline length, not engine or sail power.
5.3 kts
A displacement hull pushes a bow wave whose speed is limited by the waterline length.
With a waterline of 15.5′, the Daysailer tops out around 5.3 knots in displacement mode — after that, the bow wave outruns the hull and resistance climbs steeply.
1.34 × √15.5′ LWL = 5.3 kts
Performance Ratios
Racing handicap, sail-carrying power, stability and comfort — and what each one actually tells you about a day on the water.
Displacement / Length
69
Ultralight — responsive and fast, but carries less stores.
