The Catalina 22 is a 21. Hull Speed = Max Flying Scot is a 18′ 11″ / 5. In these conditions, the boat stays more upright than if it is sailing to windward. Flat, rounded, and multi-hull boats are displacers. For example, high-end racing sailboats are purposely designed to reach maximum speeds while larger and bulkier sailboats shallow boats and they rocket downwind and off the wind like the blazes. HS = 1. However, a sunfish will go up on Understanding Hull Speed. 34 x √LWL (in feet) Pounds per Inch Immersion: The weight required to sink the yacht The lower a boat’s Displacement/Length (LWL) ratio, the less power it takes to drive the boat to its nominal hull speed.
