SeaTow was mad because the CG was towing disabled boats, not ones truly in peril. So in other words, they were taking away customers.
My wife and I purposely make eye contact and slow down to check on boats that are just outside the channel here on the Illinois River, especially in the early season. If they look like they are adrift, or worse, have the engine cover open, they definately get a courtesy, "everything okay?"
To the original poster, if you are meeting people that are demanding money for towing you, then you are meeting total idiots and a******s. And they are actually breaking the law by asking for payment. Ask them for their salvors license the next time they ask for money. If they don't have one, and still demand money, call the Coatsies, and they will educate them on the LAW. I have to explain almost everytime that I tow someone in, that I am not allowed to accept compensation. They seem genuinely surprised, but it's the LAW. I have accepted a soda on a particulary hot day, though. Not as payment, but as a refreshment from a new friend.
