Hull Speed
The theoretical displacement-mode speed limit — determined by waterline length, not engine or sail power.
6.5 kts
A displacement hull pushes a bow wave whose speed is limited by the waterline length.
With a waterline of 23.7′, the Watkins 27 tops out around 6.5 knots in displacement mode — after that, the bow wave outruns the hull and resistance climbs steeply.
1.34 × √23.7′ LWL = 6.5 kts
Performance Ratios
Racing handicap, sail-carrying power, stability and comfort — and what each one actually tells you about a day on the water.
PHRF Rating
234s/nm
Heavy or slow cruiser — all about the journey, not the elapsed time.
Ballast / Displacement
46.7%
Race-oriented ballast ratio — very stiff and powerful.
Displacement / Length
252
Moderate-heavy — carries provisions well, deliberate in light air.
Hull Speed
6.5kts
Pounds/Inch Immersion
5lbs
Weight needed to sink the hull one inch — loading sensitivity.
