Need advice

[cmgnp]

Can anyone advise me on this, I have an old starcraft 14ft aluminum boat and have to replace the seats.
what type of wood will stand up as the brackets accept only up to 3/4 thickness.
Thanks in advance

Teak would work good.

hardwood coated with epoxy or spar urethane.

coated marine ply.

coated external ply.

Teak is the best known marine wood. Hard maple will work very well for this too.

White oak is rot-resistant and strong. It has been used in boats for a long time.
