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
Trimaran plow into the back of a wave and flip end-over-end (pitchpole). This hazard is especially dangerous for a multihull that is using a spinnaker in high winds and large seas. To avoid this unfortunate scenario trimaran sailors are advised to reduce sail and to always have all sails easily released. The use of trampolines with a large weave, to allow water to easily pass through, and the deployment of parachute anchors drogues and sea anchors whenever appropriate should reduce the risk to an acceptable degree. Several manufacturers build trimarans in which the floats can be removed, repositioned, or folded near
