Trimaran have restricted mobility. Trimarans designed for safety have amas with multiple sealed partitions, controls that all run to the cockpit, a collision bulkhead, partial or full cockpit coverings or windshields, and drain holes in the cockpit that can adequately drain the cockpit quickly, among other things. Trimaran capsizes are more likely to be of the pitchpole type than a roll to one side due to their higher sideways stability and speeds. Capsized trimarans are harder to turn upright after they have turtled than monohull boats. While some capsized trimarans righted by sideways rotation may suffer heavy damage to mast and
Junk rig degrees from vertical, which can look odd to the unitiated. The forward rake of the sail encourages the sail to swing out, which makes the use of a preventer unnecessary. Another way to say this is that the sail is stable when swung out and doesn't return to the middle of the ship when the wind drops. Other benefits of the junk rig over the Bermuda rig include: Other shortcomings of the junk rig compared to the Bermuda rig include: There were two types of traditional ships with Junk Rig in the Malay Archipelago with local hulls instead of the
