The Monhegan 48 is and competitive on the racecourse.
Hull Speed
The theoretical displacement-mode speed limit — determined by waterline length, not engine or sail power.
8.2 kts
A displacement hull pushes a bow wave whose speed is limited by the waterline length.
With a waterline of 37.5′, the Monhegan 48 tops out around 8.2 knots in displacement mode — after that, the bow wave outruns the hull and resistance climbs steeply.
1.34 × √37.5′ LWL = 8.2 kts
Performance Ratios
Racing handicap, sail-carrying power, stability and comfort — and what each one actually tells you about a day on the water.
