Is a double-rail frame that much stronger/better?
I built myself a double-rail frame because I read they were stronger.
Makes sense I guess, but now I find myself in a predicament... with my transportation arrangements it's a bit of a pain to transport my setup with the frame in one large piece so I'm debating putting break-down side-rails and converting it back to a single-rail in order to make the frame transportable in two pieces.
I'm only running up to class III+ on this boat, usually I and II. I might push up to IV, but probably not V in this boat. I have side decking I made, but I think if the cross-rails now go to the edge it will have more than enough support.
The only obvious limitation I see is that the frame is constructed with speed-rail fittings that have been drilled and pinned and oriented to prevent the frame coming apart because of fitting slip... it's just not possible at all unless a pin fails AND a set-screw loosens... and it would probably take two of each of those to actually have the frame come apart. With a single-rail, I can't see how I can set it up to be absolutely sure I have 4-direction protection.
Thoughts... opinions... suggestions?
