Because there is usually a wide separation between the hulls the trimaran yacht requires only a little buoyancy to keep the yacht stable.

Trimaran yacht stability. 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. LEEN 56 Power Trimaran. Displacement D Displacement is significant for performance and stability.

Heavy boats require wide hulls that will reduce performance over light slim ones. The wide beam of the LEEN 56 trimaran provides stability underway and at anchor. Trimarans offer better stability and a super stellar performance.

The Lowdown on Trimarans. This reason is why youd rarely find trimarans having their outrigger hulls or amas in the water. Depending on the type of monohull the weight of the ballast can often constitute 30-40 of the total displacement of the boat.

Race boats have since demonstrated that too. Echo Yachts Sorgiovanni Designs and One2three Naval Architects TSY120 120m trimaran superyacht concept delivers progressive contemporary styling advanced hybrid diesel electric propulsion arrangement with an extremely stable fast and fuel efficient trimaran hull including at speed ride control and optional zero speed Gyro motion control. A tri can accept a greater beam because its main central hull is also providing resistance to pitchpoling assuming its still in the water.

With comfort in mind her stability is such that at anchor there is little rolling and when underway heeling has been kept to a minimum even in rough conditions because of the design of the trimarans long narrow hulls. We sail fast enough to choose the weather we intend to be in. With some sailing care and extra buoyancy forward a trimaran can accept the higher transverse force of larger beam and therefore be faster.

The width of the trimaran measures 8m50 unfolded and 3m80 folded in in the harbor so he fits perfectly in a monohull berth. The wind and its influence on the performance. Generally speaking an offshore sailboat should have an LPS of 120 degrees or more.
