I'm not sure if this is true or not because I have never put it to the test..BUT..as a FYI... A lawyer friend of mine told me that if I ever got pulled over and was asked to take a breathalizer test I should say these words "I will take this test in the presence of my Lawyer". Obviosly by the time your lawyer gets to the station your b.a.l. will have gotten much better.. I know this won't rectify the problem on the water...especially getting "removed" from the boat but it may help in the long run.
It's Kind of ironic that your having this issues with marine patrol. NY just cut funding for marine patrols all over the state. I was talking to my local Sheriff the other day. He informed me they might not even put the marine patrol boat in the water this year. It's kind of good but could also be kind of bad especially if somebody gets into a jam.
