Mike has his license and he makes the loans himself so he doesn't have restrictions that normal institutes have. He also finances older boats. He did my '94 Champion. Was easy process with him all done over the phone. So he is worth taking to if you are really interested

Cash only man!
I'm 20, paid for all my boats and truck (6) in cash. Started with a kayak, jon boat, then started trading up fiberglass boats. Buy low, sell high.

You can save for 5 years and pay cash. For 5 years you just find something else to do with your free time. Alternatively, you can just finance a reasonably priced boat, make payments and have the boat for enjoyment during that 5 years for a little bit of interest. There's nothing wrong with financing as long as you don't get carried away with it.

Pay cash

Smart Young Man here!

I had the same situation! Started from simplest, the earn a little, sell the boat, buy another, better one
I've made such thing for a couple of times then stopped
I have everything I need for the time being but when it's not enough, I just take some money for credit (using https://webmoneyloans.com/, as they have good conditions), and my spouse doesn't know about that)))
everything is easy when you think about how to deal with it and ready to wait for some time
the only thing I also want to say - do not use a big credit, better save money and only take a small sum if you critically need it

Until you get out of College, think about joining a bass club with non boaters. You can learn a lot and have time to save up.
