Hull Speed
The theoretical displacement-mode speed limit — determined by waterline length, not engine or sail power.
5.9 kts
A displacement hull pushes a bow wave whose speed is limited by the waterline length.
With a waterline of 19.5′, the Oday 23 2 tops out around 5.9 knots in displacement mode — after that, the bow wave outruns the hull and resistance climbs steeply.
1.34 × √19.5′ LWL = 5.9 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
35.0%
Typical cruising ballast — balanced stability and motion underway.
Displacement / Length
206
Moderate — a good balance of speed and load-carrying ability.
Hull Speed
5.9kts
Pounds/Inch Immersion
3lbs
Weight needed to sink the hull one inch — loading sensitivity.
