Although sailing can be loads of fun, the potential hazards of water sports are also great including injuries and drowning. As the skipper of your craft, it is important to recognize that the skipper is responsible for the safety of all your crew and equipment (your boat) at all times. Ask any longtime sailors about their "stories" about what went wrong. They will have plenty. As one sails more and gains more experience, one becomes wise and more cautious in preventing potential hazards. Once you are in trouble, there are at least two things you can do to increase your safety. (If everyone followed these two basic safety rules, there would be far less drownings in the boating world.)
Will knowing the potential risks associated with water sports diminish your fun? Certainly not. Knowing the potential dangers and the following safety rules designed to keep you out of danger is the best way to insure that you have fun. Safe sailing to you!
