The X 40 is and competitive on the racecourse.
Hull Speed
The theoretical displacement-mode speed limit — determined by waterline length, not engine or sail power.
7.9 kts
A displacement hull pushes a bow wave whose speed is limited by the waterline length.
With a waterline of 35.1′, the X 40 tops out around 7.9 knots in displacement mode — after that, the bow wave outruns the hull and resistance climbs steeply.
1.34 × √35.1′ LWL = 7.9 kts
Performance Ratios
Racing handicap, sail-carrying power, stability and comfort — and what each one actually tells you about a day on the water.
PHRF Rating
48s/nm
Performance racer — quick around the cans and offshore.
Ballast / Displacement
43.0%
Stiff enough to carry a big genoa comfortably into moderate breeze.
Displacement / Length
169
Moderate — a good balance of speed and load-carrying ability.
Hull Speed
7.9kts
Pounds/Inch Immersion
9lbs
Weight needed to sink the hull one inch — loading sensitivity.
