Can a power catamaran capsize?

A Catamaran will capsize when rotational forces overcome the stability of the boat. Capsizing can happen in two ways, either the ship overtakes a wave and sinks it bows into the next one, inducing something called pitch-poling.

How big of a boat do I need to cross the ocean?

For crossing the Atlantic Ocean, you should aim for a boat that is at least 30-40 feet long. An experienced sailor can do with less. The smallest sailboat to cross the Atlantic Ocean was just over 5 feet long.

Are catamarans safer than monohulls?

Catamarans are safe for ocean crossings. In fact, catamarans are often much safer than similarly-sized monohulls offshore. Safety comes from increased motion comfort, great stability, speed, and excess buoyancy due to lack of ballast.

Who is the author of how to dimension a catamaran?

While Part 1 showcased design comments from Richard Woods, this second webpage on catamaran design is from a paper on “How to dimension a sailing catamaran”, written by the Finnish boat designer, Terho Halme. I found his paper easy to follow and all the Catamaran hull design equations were in one place.

How many kW does a catamaran engine use?

The engine power needed for the catamaran is typically 4 kW/tonne and the motoring speed is near the hull speed. Installed power total in Kw motoring range in nautical miles R m = 600, A diesel engine consume on half throttle approximately: con := 0.15 kg/kWh.

Is the beam of a catamaran too wide?

The beam of a sailing catamaran is a fundamental thing. Make it too narrow, and she can’t carry sails enough to be a decent sailboat. Make it too wide and you end up pitch-poling with too much sails on.

What’s the loaded displacement mass of a catamaran?

Loaded displacement mass in kg’s L DR near five, the catamaran is a heavy one and made from solid laminate. Near six, the catamaran has a modern sandwich construction. In a performance cruiser L DR is usually between 6.0 and 7.0. Higher values than seven are reserved for big racers and super high tech beasts.
