It could be done, but it'd probaby be a lot easier just to get a old boat like you want, and re-do it.<br /><br />You've probably seen boats with rotten floors/transoms, and bad motors around. If you can find that combination before it makes it's way to the scrapyard-- they're real cheap.<br /><br />I've seen (project)hulls & trailers that might do what you want a boat to do go on e-bay for 2-300 bucks, with a trailer. <br /><br />Changing a hull like you're proposing is a BIG! project not to be taken on without a lot of pre-planning and some counciling from folks who are expert at doing that sort of thing. <br /><br />Ed.Originally posted by ddaigle:<br />Any ideas on installing a tunnel in an aluminum bay boat for shallow running? Down here in south texas the water is real skinny where the fishing is good.
