Hull Speed
The theoretical displacement-mode speed limit — determined by waterline length, not engine or sail power.
8.4 kts
A displacement hull pushes a bow wave whose speed is limited by the waterline length.
With a waterline of 39.0′, the Sweden Yachts 45 tops out around 8.4 knots in displacement mode — after that, the bow wave outruns the hull and resistance climbs steeply.
1.34 × √39.0′ LWL = 8.4 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
41.9%
Stiff enough to carry a big genoa comfortably into moderate breeze.
Displacement / Length
205
Moderate — a good balance of speed and load-carrying ability.
Hull Speed
8.4kts
Pounds/Inch Immersion
11lbs
Weight needed to sink the hull one inch — loading sensitivity.
