Hull Speed
The theoretical displacement-mode speed limit — determined by waterline length, not engine or sail power.
7.1 kts
A displacement hull pushes a bow wave whose speed is limited by the waterline length.
With a waterline of 27.8′, the Robinhood 36 tops out around 7.1 knots in displacement mode — after that, the bow wave outruns the hull and resistance climbs steeply.
1.34 × √27.8′ LWL = 7.1 kts
