Repair of Damage to Gel Coat Layer on Hull Bottom

I wasn't paying attention and ran the boat onto on some submerged rocks--at slow speed, thankfully. Until I pulled the boat off the grinding was disheartening.

After siting at the dock in saltwater for a couple days, I pulled the boat. I saw some gouges on the bottom. One spot is the size of a pencil eraser. I can see some dark color--fiberglass, I guess.

Give suggestions on the repair procedure. Is a repair even necessary?

Thanks.

If the gel coat layer has been abraded away and the underlying laminate layers are exposed, a repair should be made.

Because the damage is on the hull bottom and will be perpetually underwater when the boat is in use, a repair is necessary. The gel coat layer is considered a water-resistant layer, but the underlying laminate layers are not water resistant. As the repair generally will not be visible, making a completely perfect cosmetic repair won't be mandatory.

For advice on how to make minor repairs to a Boston Whaler, there are three good articles. Here are the links.
