Hull Speed
The theoretical displacement-mode speed limit — determined by waterline length, not engine or sail power.
5.5 kts
A displacement hull pushes a bow wave whose speed is limited by the waterline length.
With a waterline of 17.0′, the Northbridge Eclipse Southcoast tops out around 5.5 knots in displacement mode — after that, the bow wave outruns the hull and resistance climbs steeply.
1.34 × √17.0′ LWL = 5.5 kts
Performance Ratios
Racing handicap, sail-carrying power, stability and comfort — and what each one actually tells you about a day on the water.
Ballast / Displacement
27.8%
Light ballast — tends to be tender; reef earlier than the numbers suggest.
Displacement / Length
164
Moderate — a good balance of speed and load-carrying ability.
Hull Speed
5.5kts
Pounds/Inch Immersion
3lbs
Weight needed to sink the hull one inch — loading sensitivity.
