Re: For those boats that have seatbacks, what is the angle from the seat to the backrest?

quote Outboard315:

.25″ that is slightly overkill. Make it from .100″ aluminum and put an arch in it and maybe bead roll a design in it.

I’m worried that the seatbacks will end up pulling the mounts out after time. Additionally putting a debossed/engraved design in the seat face will either need a special mold, or thicker metal so I can cut the design into it. That would mean tools I don’t have or have access to yet

I’m working with what I have, basically

quote amuller:

That’s a lot of work. I would gin up something out of plywood with an adjustable backrest angle and do some experimenting. See what works for you. Also, you’re in Florida. Aluminum seats with get hotter than hell in the sun. Another approach could be to get some old boat seats and experiment with height and angles. Or a pair of front car seats from a small car (U pull it junkyard).

It won’t be much work, actually. Casting will be the most labor intensive process for me, I’ve got access to a CNC router that will cut aluminum plate. I was planning on roughing out something in plywood so I could test fit it.

I did think about the heat of aluminum, but the seats are already made of aluminum and I don’t want to ruin the aesthetic of an old boat. I’ll just keep a towel in the boat to sit on.
