The International Hobie Class Association (IHCA) has issued an updated rule book which includes some minor changes. The most significant change is to the Hobie 16 class rules which states:
Trapeze wires shall be of stainless steel wire of not less than 2.38 mm diameter. The minimum length of the trapeze wire, including shackles, shall be from the bearing point on the mast tang to a point 1250 mm above the base of the mast extrusion. Adjustable systems may be attached to the trapeze wire shackled to the mast tang.
This change was made to close a loophole which some racers were using to have trapezes made from synthetic line.
