The sections aft are designed to support the full aft cabin configuration with buttock lines that run out at a milder angle.

Narrow catamaran hull. The twin hull design of our power catamaran produces a narrow footprint in the water when compared to a mono hull design. Americas Cup AC72 Design - Narrow Hull Catamaran. I got to take a ride on Wind Horse today and was very impressed.

The IC36s unique narrow hull shape below the waterline is derived from the same design thinking that goes into todays high-speed racing catamarans. But above the waterline you will experience the comfort of a cruising catamaran with a high-volume hull. Yet another saving on the running costs.

This produces a faster better-supported hull. Both are totally impractical. The design concept comprises a narrow long hull that cuts through waves.

In contrast the modern catamaran. Make it too wide and you end up pitch-poling with too much sails on. Narrow hulls give you lower hydrodynamic resistance and higher top-end speeds.

However this drag formula is generally not the limiting factor for catamaran hull speed. Beam of sailing catamaran. It primarily depends on beam and individual hull buoyancy for stability.

For a smooth passage through the water your catamaran needs slim hulls. A catamaran s light narrow hulls slice the sea with little resistance while the twin hulls wide stance provides enormous stability at low heel angles. Most early narrow-beamed catamarans suffered from this phenomenon Ultimately a boats design has a major influence on its ability to stand against the forces of nature and to keep occupants safe.
