Apply the paste to the damaged area, filling the hole or gouge to the original level. Most modern epoxys and resins are designed not to shrink, so you don't want to overfill the hole.

To do that, cut the screen to fit the hole and force the epoxy or resin into the screen with a squeegee so that all the holes are filled. Then lay the the screen in the damaged area. If the hole is deep enough, you may want to lay several layers of screen on top of one another.

Dave first used neat epoxy—straight, with no fillers—to wet out the area around a hole.

The largest mat circle went down first, followed by the equivalent size cloth circle, and so on, alternating layers of mat and cloth. The mat builds bulk in the laminate, while the cloth provides structural strength.

Hi there, I'm new to the forum and equally new to boat restoration or in my case, repair. I really need some advice on what the best method is on fixing this hole I have in the boats hull. I have no great experience in any kind of woodworking, and I don't have every type of snazzy powertools at hand.
frosh Senior Member

All may not be lost. (Emphasis on "may") It looks like someone took the cheap and easy way out last time.
Oldgold New Member
Thanks alot for the advice everyone. Apart from this "limited" 12" x 6" hole the hull is other sound so to be honest that's a stroke of luck. There's some superficial damage to the deck like peeling varnish and a bit of bad ply but thats not too much of an issue.

Yes. I just looked closer, and you're right. I deleted the whole thing a minute ago, before reading your comment after. Wait for more photos and info.

Condolences. The sails, hardware, spars, and rigging must be okay. A new hull could be built by strip method. In a small sailboat, using cedar strip/epoxy, the hull isn't that time consuming nor expensive as all the rest, and you do have what is probably an excellent pattern.
