What's the best backing plate material? Whaler uses a material "phenolic" for backing under the deck for cleats, behind swim platforms, etc. If that material is available, I would think it would work well. I suspect there is a generic term for that product. Anyone know what it might be called?

If you are going to cut a hole in the floor forget the togglers. Though bolt it and be done. The togglers are used to bypass the access hole.

Stainless would be the best material, it's to easy to strip the threads in phenolic. Don't try to use nuts and washers you'll drive yourself nuts, go with 2 half moon flanges with tapped holes. Make a nice thick epoxy paste to glue the flange to the underside of the deck (use short bolts to hold it in place until the epoxy cures). If the foam goes to the underside of the deck some can be dug out, just seal the foam after digging.

Just be sure there isn't a sringer or bulkhead where you want the seat, Grady should be able to send you some drawings.

Interesting, my old boat, I installed the pedestal in the floor with #12 SS Sheet metal screws. Largest I could find. The floor was carpet covered, thin layer of glass and 1/2" ply. I beat this boat in seas for years and never did the seat pedestal come loose. When I removed the base to put in new carpet, the screws were extremely tight.
My point here is that it seems to me, the spread of the pedestal base and all the screws working together, you should not have an issue in tearout unless you hit a 10' wave and a 250# guy falls on it sideways? :mrgreen:

Just sayin'........
