Never worked on aluminum hulls, well not too much anyways, but I would suspect that any aluminum side braces that go from the gunwale to the floor structure would stiffen up the gunwales perfectly. JMHO.
I'd like to tag along if that is okay.
Welcome to the Statmada :wave:
You have a good blank slate to start with but don't get too far ahead of yourself, there's lots of work to do on the hull normally before decking ever goes in.
Thanks for the welcome, I'm glad I found this resource of very talented people!
Funny you should mention that, I caught myself skipping weeks ahead of my prep work today, sat back, took a deep breath and had a long talk with myself. I think I have me under control for now, but will do some, "musing out loud" here on the forum and if you all see me about to mess up, whack me with a 2x4!
