Bare Hull business as it is called has declined a lot in the US over the years. This is mostly because of the cost associated with boat production in the US compares to off shore, as well as overall consolidation in the industry.

You should google: '"Bare Hull" boat'

and can find some links, such as: http://www.sailingtalks.com/.../...ll-suppliers.html

If you are looking for a power boat, larger one, and live near a fishing community, you might ask around to see if there is mold available somewhere.

Another idea, depending on where you live, you might try looking for someone who has started to Home Built and ran out of gas... Try the local paper, Craigslist, etc.

Homebuilts typically have something like a 1:1000 completion ratio, so there are lots of 'in the works' projects out there just taking up space. You might be able to get a good deal on not only the hull, but some other things as well, ala steering, motor, etc... It is not uncommon to get these to 1/10 the 'cost' that was put into the project.

Another idea: Walk the docks at a local marina. Look for 'Dock Queens'. After a few years of paying moorage, one can often find a good boat in need to care that can be had for a very reasonable cost.

One thing to keep in mind: in the overall costs, the bare hull is a small % of the total. So, if you are looking to get a boat 'cheap', the best way is find a fixerupper as it already has most everything you need. Even if you refresh many of the systems, it can be more cost effective then starting with just a hull.

Good luck!
