Hull Speed
The theoretical displacement-mode speed limit — determined by waterline length, not engine or sail power.
8.5 kts
A displacement hull pushes a bow wave whose speed is limited by the waterline length.
With a waterline of 40.0′, the Moody 45 Classic tops out around 8.5 knots in displacement mode — after that, the bow wave outruns the hull and resistance climbs steeply.
1.34 × √40.0′ LWL = 8.5 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
28.9%
Light ballast — tends to be tender; reef earlier than the numbers suggest.
Displacement / Length
176
Moderate — a good balance of speed and load-carrying ability.
Hull Speed
8.5kts
Pounds/Inch Immersion
12lbs
Weight needed to sink the hull one inch — loading sensitivity.
