The Swift 40 is designed for cruising comfort rather than racing.
Hull Speed
The theoretical displacement-mode speed limit — determined by waterline length, not engine or sail power.
7.5 kts
A displacement hull pushes a bow wave whose speed is limited by the waterline length.
With a waterline of 31.0′, the Swift 40 tops out around 7.5 knots in displacement mode — after that, the bow wave outruns the hull and resistance climbs steeply.
1.34 × √31.0′ LWL = 7.5 kts
Performance Ratios
Racing handicap, sail-carrying power, stability and comfort — and what each one actually tells you about a day on the water.
PHRF Rating
171s/nm
Typical cruiser — designed for comfort and ease, not podium finishes.
Ballast / Displacement
36.8%
Typical cruising ballast — balanced stability and motion underway.
Displacement / Length
364
Heavy displacement — a slow, steady, seakindly hull.
Hull Speed
7.5kts
Pounds/Inch Immersion
9lbs
Weight needed to sink the hull one inch — loading sensitivity.
