Pulled 20 year old houseboat out of water for the winter to find this.IMG]http://i202.photobucket.com/albums/aa287/mkmohn/DSC04149.jpg[/IMG]IMG]http://i202.photobucket.com/albums/aa287/mkmohn/DSC04148.jpg[/IMG
]Am I correct in thinking that the Gel coat has worn off, and I'm down to the fiberglass? Can I simply put more gel coat on?
Another forum suggested that Gibson houseboats should not be beached due to thin bottom, could I add more layers of fiberglass and then gelcoat?
What are your suggestions?
We do some beaching...half dozen times a summer. Boat is out of water half of the year.
 
get the bottom completelty sand blasted, then apply Interlux's Interprotect 2000 series to barrier coat following directions, then apply desired bottom paint

What he said.

Also, if you continue beaching the boat, the barrier coat isn't gonna last long. If you insist on beaching rather than anchoring, you should add a KeelGuard. It is a protective rubber strip that protects the boat bottom from this precise problem.

I would provide a Boatfix link, but a cant seem to find it on their site.
 
Do what the rest of us houseboaters do and use coal tar epoxy on the bottom. Blast it, make sure it it dry, and lay 3-4 coats of coal tar epoxy on it. It will stand up to the beaching. It only comes in black though.
 
I'd fix the "chunk" that's out of the keel also while I was at it.
 
It looks like a chunk is out, but its an optical illusion. The dark spot is part of the blocking.

What is coal tar epoxy? I haven't heard of that before?
 
It is a two part epoxy. It only comes in black. It is used on barges, bridges, and such. It is also used on steel and fiberglass houseboats. It makes one heck of a barrier coat. Google it.
 
I'd build up the area with a couple extra layers of fiberglass to protect it in the future. Then coat as above.
