Hull Speed
The theoretical displacement-mode speed limit — determined by waterline length, not engine or sail power.
4.6 kts
A displacement hull pushes a bow wave whose speed is limited by the waterline length.
With a waterline of 12.0′, the Banshee 13 tops out around 4.6 knots in displacement mode — after that, the bow wave outruns the hull and resistance climbs steeply.
1.34 × √12.0′ LWL = 4.6 kts
