• the loop integral with the cable can easily escape from the hook, making it possible to free the team member to perform the necessary maneuvers, and in particular to change the edge.
• the team member may not be able to detach from the loop, and be in a delicate situation. Few but sometimes fatal accidents occur regardless of the skill level of the practitioners. These accidents often occur when boats overturn, and crew members fall into the water. Team members can then be trapped under the boat or under the sails, without the possibility of getting free, blocked by the tension of the trapeze cable which prevents the release of the hook.
• a team member falling from the boat, may find himself hanging by the hook on a rope in tension in the boat.
• This accessory can be the low hedge in the case of a dinghy, or the transfiling of the trampoline in the case of a catamaran.
• the common point is that the team member has a very short time to free himself before being trapped under the boat, which he often contributes, by his own weight, to accelerate the capsizing. Risk situations are multiplying today, to the extent that there are an increasing number of boats which are more and more rapid and unstable, and which require the use of the trapeze for both the crew member (s) as for the coxswain, as part of a solo or double practice.
