In order to exert the maximum righting leverage, many boats are provided with racks, a trapeze wire, or both, to enable the crew to move further out. Trapezing is generally less tiring than hiking. Most trapeze boats are equipped with spinnakers. There are a few exceptions, including some multihulls.
A good harness should fit snugly and offer minimal opportunities for snagging on rigging, etc. The hook should be positioned near your centre of gravity (facing down), and hooks into a ring suspended from the trapeze wire. The ring will be of adjustable height so that you can raise and lower yourself according to the amount of leverage required and whether you are positioned forward or back. Good non-slip footwear is essential.
