I find it surprising how many folks borrow money to buy toys, but I guess it's the American way. The old argument of investing your boat money and financing the boat is poor financial planning. You should pay cash for your boat from the good investments you've made. If you absolutely must finance one, use a home equity loan, cheaper and you won't have to insure it. But get rid of the debt asap. I could see an absolute steel comes up now and then, I suppose one could justify borrowing to make the deal.
Finance investments, things that MAKE money. Pay cash for toys, cars, boats, planes, etc.
