The general rule of thumb is that banks won't loan for the purchase of a boat over 30 years old. As alluded to above, there are loans available for older boats that are typically at higher rates, but not typically from a bank, per se. But, if you have a business or significant personal relationship with a bank (especially a smaller community bank) you may find cooperation. As always, credit score, appraised value of the collateral, insurability, favorable survey and downpayment drive that bus. A knowledgeable broker or a marine insurance company would be a good place to investigate sources of capital.
