Hull Speed
The theoretical displacement-mode speed limit — determined by waterline length, not engine or sail power.
9.7 kts
A displacement hull pushes a bow wave whose speed is limited by the waterline length.
With a waterline of 52.1′, the X 612 tops out around 9.7 knots in displacement mode — after that, the bow wave outruns the hull and resistance climbs steeply.
1.34 × √52.1′ LWL = 9.7 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
42.3%
Stiff enough to carry a big genoa comfortably into moderate breeze.
Displacement / Length
150
Ultralight — responsive and fast, but carries less stores.
Hull Speed
9.7kts
Pounds/Inch Immersion
19lbs
Weight needed to sink the hull one inch — loading sensitivity.
