Hull Speed
The theoretical displacement-mode speed limit — determined by waterline length, not engine or sail power.
7.2 kts
A displacement hull pushes a bow wave whose speed is limited by the waterline length.
With a waterline of 28.7′, the Parker 325 tops out around 7.2 knots in displacement mode — after that, the bow wave outruns the hull and resistance climbs steeply.
1.34 × √28.7′ LWL = 7.2 kts
Performance Ratios
Racing handicap, sail-carrying power, stability and comfort — and what each one actually tells you about a day on the water.
Ballast / Displacement
34.0%
Typical cruising ballast — balanced stability and motion underway.
Displacement / Length
148
Ultralight — responsive and fast, but carries less stores.
Hull Speed
7.2kts
Pounds/Inch Immersion
6lbs
Weight needed to sink the hull one inch — loading sensitivity.
