I don't agree that having a boater's card makes the waters safer at all. There will always be accidents no matter how many tests you take or how much knowledge you have. An accident is just that. There are avoidable tragedies cause by people drinking or people just not being careful. Then of course there are a few people who are just plain too scatterbrained to drive any kind of a vehicle on public roads or waterways. The cards were not put in place to make the waterways safer. They were a stop gap measure to get people, mostly on PWC off the water. They started with the PWC then every couple of years expanded it to include longer and longer boats 'til we got to where we are today. Almost everyone has a card, there is no central registry for the card and with or without a central registry, the card is still a useless measure. One blatant example is that people who've had their own boat on the water for 40 years need a card...folks who are renting a boat for the very first time, don't need a card. Where's the logic there? There is none. I could go on but it's not worth it. You cannot legislate common sense. Stupid people will cause accidents with or without a card. And the accidents (in the true sense of the word) will happen even between two very knowledgeable boaters.
