Hull Speed
The theoretical displacement-mode speed limit — determined by waterline length, not engine or sail power.
6.2 kts
A displacement hull pushes a bow wave whose speed is limited by the waterline length.
With a waterline of 21.4′, the Us 25 tops out around 6.2 knots in displacement mode — after that, the bow wave outruns the hull and resistance climbs steeply.
1.34 × √21.4′ LWL = 6.2 kts
Performance Ratios
Racing handicap, sail-carrying power, stability and comfort — and what each one actually tells you about a day on the water.
PHRF Rating
219s/nm
Heavy or slow cruiser — all about the journey, not the elapsed time.
Ballast / Displacement
33.3%
Typical cruising ballast — balanced stability and motion underway.
Displacement / Length
170
Moderate — a good balance of speed and load-carrying ability.
Hull Speed
6.2kts
Pounds/Inch Immersion
4lbs
Weight needed to sink the hull one inch — loading sensitivity.
