Bank of The West has been financing boats for many years. Don’t know their rates right now, but last I remember, they were competitive and offered long terms if that’s what you’re after.
On my current boat I went with State Farm. Yes the insurance company. They have State Farm bank too.
I already had State Farm and was getting a quote for insurance from them for my new boat and they asked if I would like to get my boat loan through them too. I thought it would be high interest and I could only take it out to 36 months. But I was wrong the rates where really good and I "could" take it out to 12 years. I didn't but I could have.
Now I have all my auto loans through them. It's very easy and all the transactions are done through your Insurance agent.
Pentagon Federal Credit Union has my current boat. I’m a member of 5 credit unions and they were pretty hit or miss on boat financing. Pentagon Federal was the only one I talked to that would give me a good rate and good term on a 2011. On the auto side PFCU will finance almost any age collateral as long as its book value works out and you have a good enough credit score. I think that’s why they weren’t afraid of an 8 year old (at the time) boat. Two of the credit unions flat out wouldn’t touch it due to age. One wanted a 5 year term. One wanted 50% down.
