"Holt Allen buoyancy bags are made from tough and tested 0.16 in. thick PVC and come in a variety of shapes to fit snugly in your dinghy. Each bag has welded strap loops and a flexible screw cap and nozzle with a slow return valve to aid inflation. Important Fitting Instructions: After checking that there are no sharp points to snag, the bag should be firmly secured to the dinghy by webbing straps passing over and round the bag through the positioning loops. Do not use the loops for actual attachment.*Tips on Buoyancy Bags: Make sure there are no sharp points in your boat that would snag or puncture the bags (especially check the undersides of any structures). Bags should be attached to the boat by passing webbing straps over and around the bag through the positioning loops on the bag. DO NOT use the loops for the actual load bearing attachment to the boat. Leave your bags slightly underinflated to ensure they do not rupture as the air inside expands on hot days. All dimensions quoted are approximate inflated sizes. Buoyancy is approximate as provided by the manufacturer."^^<http://www.w3.org/2001/XMLSchema#string>
