Seat pedestal mounting question

[Thehustler]

Hi am just finished installing a new floor and stringers and foam in my boat. It's a 94 caravelle ski boat. I am wondering the best way to mount the seats so the floor doesnt rot. I was thinking of some how gluing a square 2-3" thick piece of wood to the floor and mounting them to that so I don't have to drill holes in the new floor with chances of taking in water and rotting or if I should just screw them directly to the new floor and try and seal them off. Please help me if u can thanks for the help

I'd recommend applying an additional layer of 3/4" (pre-wrapped w/ CSM and polyester resin) to the deck directly where you want to put the pedestals. Then fiberglassing them to the deck:

Use the correct size stainless T nuts on the backside of the additional 3/4" ply and bolt the seat pedestal in place

Sounds like a viable option to me to install those resined and glassed in supports shouldn't above by jbcurt00 posted. There are tons of ways to accomplish doing what you are asking. So select one and follow their prep and installation techniques and you'll enjoy years of rot-free mounts. Those look nice clean and sealed well designs... JMHO!

You just build them yourself. I made mine out of plywood... several layers to achieve the desired thickness, cut on a bevel. There's a bit of discussion on this in my restoration thread (see link below in my signature). If you look at posts 92-113 there is discussion of how to make the bases (shape, etc.) and then in posts 140-151 you can see what they look like glassed onto the floor. If anything isn't clear, or if that brings up additional questions, I'd be happy to answer them, if I can.

Best,
Jim
