My rule of thumb is don't buy anything that I am unable to pay cash for. With that said, I don’t pay cash for everything. If you can make money elsewhere with the cash, then finance the boat. Today it may be a different story because it is hard to make money, but I still have liquidity. If I had that money in my boat, I am not getting it out any time soon. Cash is King, especially when it is in the bank not the boat!
