Trimaran Marine Unit. Littoral combat ships built by General Dynamics at Bath Iron Works are of a trimaran design. USS "Independence" (LCS-2) is the first of these ships. Littoral combat ships built by Lockheed are of a monohull design. First launched on 31 August 2012 at Bali Strait, 63M Carbon Fibre Composite Trimaran Fast Missile Boat (Indonesian: Kapal Cepat Rudal [KCR]) named KRI Klewang (625) – a traditional Indonesian single edge sword, was the first stealth trimaran of the Indonesian Navy built by North Sea Boats at Banyuwangi, East Java, Indonesia. This ship combined a number of existing advance technologies into
Pontoon effect a trimaran with narrow-beam floats will simply submerge the lee float, exposing only the weather wing and that with a lesser moment. In practical sea situations the windage effect is greater than the buoyancy effect and so cruising trimarans with highly buoyant floats are more, not less, likely to capsize than those with less buoyant floats. A trimaran is best stabilised not by adding buoyancy on the lee float but adding weight to the weather float. This is the basis of the "cool-tubes" stability system invented by Tristan Jones and L. Surtees. A large-diameter pipe closed at the aft end
