Re-finance boat on credit card?

I got a CC offer in the mail yesterday at 0% for 12 months. I can write a check for myself with a max fee up to $75. So I started thinking…..What are the downfalls if any. I want to pay off my boat loan with the credit card check. This way I can pay my monthly payment but at the end of 12 months have paid down my principal significantly, then just re-finance (the remaining balance) near the end of the CC term. Anyone ever done this? I’ve bought smaller boats (under 15k) on CC’s but never something like what I have now.
