Ply battery mount
Submitted by bergerac on Mon, 2013-09-16 15:52
Im looking at putting a second battery in my fibreglass runabout but because the floor in this boat sits down low within the hull I dont quite have enough room. I was thinking of making a marine ply platform that sits up off the floor on one side and rests in the corner of the hull on the other and fixing the batteries to that. I'm just wondering will I need to do anything to seal the ply since its going to be in a potentially wet area? And will screwing it to the existing floor also be enough or will I need to use epoxy or something similar to make sure it holds. Hoping I dont need to start fibreglassing mounts to the floor or anything like that.

You could fiberglass the
You could fiberglass the piece of plywood down and coat the while bit with epoxy? Really easy job.

If your screwing anything
If your screwing anything into the floor - particularly in a wet area you want to make sure its well sealed so water doesn't get into the floor and start rot - from that point of view silicone or marine sealant may only seal for a given time and fibreglassing it down may be the better option.

Seal it
You could seal it with polyester resin and then glass in the structure to the floor and sides. Make sure you rough up the contact surfaces of the boat prior to glassing though. Then flowcoat the resin coated plywood with the colour matched to the existing. For example:-

Thanks guys I didnt think
Thanks guys I didnt think about the water ingress into the floor, do I need to remove the gelcoat from the areas of the floor when Im attaching the mount or will just roughing it up do the job?
Ideally I would just remove the moulded seats and do something similar to the pic about but its hard enough to get time to do the small jobs at the moment.

Not long
Bergerac,
That shelf took all of three hours of work. The hardest part for me was getting the sides to fit under the transom wells. Once you have them fitting nicely, you resincoat the ply, glass the joins and once that goes off, you flowcoat the whole thing. Simple really.
It would be a good idea to remove the flowcoat on the floor or at least grind it down so the glass has something to grip on to.
PM me if you have any questions.
