It is important to note that the max stability of the tri occurs at around 20 degrees angle of heel while the cat has a max at about 6 degrees.

Trimaran yacht stability. Generally speaking an offshore sailboat should have an LPS of 120 degrees or more. Thus even in rough seas the shape of the floats makes the recreational trimarans particularly stable and comfortable to sail. The trimaran has less accommodation and is lighter than the cat but because of the wider beam it has greater maximum stability.

For trimarans it is the distance between the main hull and one outrigger for performance considerations and between the centerlines of the two outriggers for stability considerations. Of course greater beam of the entire superstructure of a typical trimaran has a dramatic effect on the hull stability and increased righting moment. To summarize we often sail on two of the three hulls but never on one.

The wide beam of the LEEN 56 trimaran provides stability underway and at anchor. Trimarans offer better stability and a super stellar performance. The wind and its influence on the performance.

LEEN 56 Power Trimaran. With some sailing care and extra buoyancy forward a trimaran can accept the higher transverse force of larger beam and therefore be faster. A tri can accept a greater beam because its main central hull is also providing resistance to pitchpoling assuming its still in the water.

LEEN 56 - a 21st Century Hybrid Motor Yacht. Depending on the type of monohull the weight of the ballast can often constitute 30-40 of the total displacement of the boat. We sail fast enough to choose the weather we intend to be in.

Designed by John Shuttleworth Design. Such a design makes trimarans incredibly stable meaning theyre. On the contrary the 3 hulls of the pleasure trimaran give it great stability like the small wheels you add to a bicycle.
