I have a folding seat for my aluminum boat that is broken. The seam between the two bottom pads has ripped apart after just a few uses.
I want to build my own version of the seat out of plywood (like this or this). I want the seat to be strong enough for me (big and tall) to really lean into it. Also, a solid plywood seat would be easier to position on a narrow boat seat, without the back corners slipping off the back of the boat seat.
The parts I like about that fabric seat are 1) the rigid frame for leaning/sitting back (especially the top cross member) and 2) the adjustable strap. I can easily tighten or loosen the strap with one hand while sitting in the seat. So I'll keep the general design of the seat, just replace the back and bottom with plywood.
I want to buy a strap buckle (for lack of a better word) that is made of metal since I suspect the plastic buckle from the old seat will break over time -- due to the elements and from me leaning forcefully into the seat.
What is the proper term for the strap buckle?
