I've done this a couple of times. I purchased my first boat with a business partner. We actually ran payments and costs through our company. The boat had quite a few problems though - had to move everyone to the front to get her to plane 🙂 But, we kept it for about a year before trading it in on anther boat which we also shared. We kept in close communication about issues that inevitably came up and shared costs evenly - which I would highly recommend. Any new items/costs had to be agreed on prior to purchase and everyone shared equally. If you have a good relationship with your potential partners, I would encourage you to continue your exploration. Good Luck.
