Is this a fairly good idea if I'm building a boat myself?
My plan is to lay the keel this spring, if everything goes well. Originally, I was planning on building the hull, then flipping her, and putting her on her trailer, however, the only trailers I can find for a 30' boat run about $5000, which is a lot more than I was planning. If I need a trailer immediately after the hull is done, then I probably have to push back construction a bit...

I was thinking I might be able to build what amounts to an inverse strongback to hold the boat right side up while I work on finishing the hull, and mount the engine. That way I can buy the trailer as a last step, which gives me a bit more time to save up that extra money.
Thoughts? Or is this a mistake? I've never built a boat before, of any kind, and would appreciate the voice of experience from those who have!
