ON-WATER PRACTICE
Picking Up a Tow Tow boat approaches slowly to the windward side of the sailboat pointed in the same direction.
Throw or hand over the towline, or drag the towline by the sailboat. When the towline is secured (wait for the okay visual signal), take up slack gently and proceed to the next sailboat.
Maneuvering with a Tow E Changes in speed, stopping and starting should be done slowly. E Wait until all boats on the tow are moving and towlines are clear before maneuvering.
E Keep a lookout posted to watch the tow behind you. E Keep the towing speed low. E Turn in large arcs, using a turning radius approximately equal to the length of the tow.
E Adjust the towline so the first boat in a line is not being pulled up the backside of a wave (to help reduce load on the tow boat).
E If a boat falls off, keep the tow moving slowly; don’t stop and let the boats bunch up.
E If conditions are rough, increase control by lengthening the towline or slowing the speed to increase the catenary (droop) of the towline.
E Remind students of the expected behavior while under tow. E Be aware of the possibility of fouling the towline in the propeller. E Be aware of the possibility of overhead power lines.
Casting Off a Tow When sails are raised under tow (which is not recommended for beginners or in windy or rough conditions), the tow boat should head into the wind and move slowly while sails are hoisted. When the sails are up, the tow boat should keep the apparent wind forward of the beam but not in the No-Go Zone. Boats drop off, starting with the last boat on the tow.
Anchoring the tow boat is a slower method, but it provides better control for beginners or rough conditions. The tow boat anchors, sailors then raise their sails and cast off. In light winds, sailors can cast off before their sails are raised and hoist sails while drifting.
