Help with wiring and flooring

[billdc]

I have a Ski Brendella, but I've been told I might find some help here. I picked this boat up in the spring and the PO had left it uncovered for two or three years. I already own a bowrider that we use almost every weekend, so this boat will sit at a local river for weeknights and occasional short weekend trips. I have two 13yo that want to ski and board, so I might have this boat for 5-6yrs, and I might end up keeping it longer if everyone likes it. I am going to start the renovations on it soon and I think I have some questions for those who have gone before me.
I want to replace the floor and got some info on this

Seems to be rot proof, but is it worth the extra money. I have a local supply of marine and ACX plywood that would be alot cheaper (materials and shipping), but I want to make sure I'm doing it right.

The PO also rewired the panel to support a stereo and amp, by disconnecting the bilge and blower and removing the switches. I was thinking of a panel that like this.

I'm sure I will be back with more questions because I don't even have the boat in the driveway yet, but I'm starting to put together a plan of attack. Thanks

I would go with the composite material. What ever route you take, make sure you take out the original foam. It's open cell foam, so it absorbs and holds water -- ultimately rotting anything it comes in contact with. Can't imaging why any boat manufacturer would use open cell foam on a boat. It's really is a bad idea -- they weren't thinking, and it's cost a lot of headaches for older boat owners.

Going with plywood, fiberglass and resin is a tried and true method that can be very strong, and weather proof if done right. Without knowing how your boat is constructed, the best thing I could recommend is to search this forum and read through all the rebuilds. See how that applies to your boat, needs, and budget.

even the closed cell foam will absorb water over time ... the lesser evil when your boat is swamped (vs. sinking to the bottom).

I can't imagine how open cell foam would keep your boat from sinking, or any foam for that matter. Not enough flotation.
