The Tartan Tock 40 is designed for cruising comfort rather than racing.
Hull Speed
The theoretical displacement-mode speed limit — determined by waterline length, not engine or sail power.
7.6 kts
A displacement hull pushes a bow wave whose speed is limited by the waterline length.
With a waterline of 32.3′, the Tartan Tock 40 tops out around 7.6 knots in displacement mode — after that, the bow wave outruns the hull and resistance climbs steeply.
1.34 × √32.3′ LWL = 7.6 kts
Performance Ratios
Racing handicap, sail-carrying power, stability and comfort — and what each one actually tells you about a day on the water.
