It’s kinda of buried right now. I made the trailer as a break down type. Axle is square tubing that stub axles slip into and held in with pins. Tongue also separates from axle with a pin. Bunk brackets are welded onto axle and 18” 2x4 for bunks and a rubber roller is on tongue. 3 straps hold boat onto trailer, 2 at back down to hoops in axle and 1 at the front. Although trailer breaks down, I have yet to actually do it and just load it as is.I see your boat following. I want to do the same . With 12 foot jonboat.
Any recommendations for trailer design? Any pics of yours?
