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 Northshore 33 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
