Make sure your equipment is in safe, serviceable condition. Foot bindings should be secure and free of sharp or protruding surfaces. Skis made of wood should be free of splinters or cracks in lamination. Check your towline (handles, lines, and connecting hooks) for strength every season. Attach towlines only to proper fittings on the boat. Many skiers have been seriously injured in accidents with the towboat or ski equipment. A moving towline can cut like a knife. For this reason, towlines should be of equal length when more than one person is skiing.
