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 29.7′, the Swan 371 tops out around 7.3 knots in displacement mode — after that, the bow wave outruns the hull and resistance climbs steeply.
1.34 × √29.7′ LWL = 7.3 kts
