The Cs 40 is and respectable in club racing.
Hull Speed
The theoretical displacement-mode speed limit — determined by waterline length, not engine or sail power.
7.7 kts
A displacement hull pushes a bow wave whose speed is limited by the waterline length.
With a waterline of 32.7′, the Cs 40 tops out around 7.7 knots in displacement mode — after that, the bow wave outruns the hull and resistance climbs steeply.
1.34 × √32.7′ LWL = 7.7 kts
