Default Boat Hull - paint chipped off, exposed fiberglass a problem?

Im new here. Cant upload pics yet. There is foot long area where paint chipped and what looks like exposed fiberglass right at the very bottom ridge of the boat. Does that need to be repaired before i put her on the water again ? Sorry, newbie boat owner here. 1984 bayliner ciera 2450. Any help would be appreciated.

If you have the boat in the water all season, it should be repaired before getting it in. If you trailer the boat you can fix it during winter if you want to. Since it's where no one sees it, I'd just fix it myself:

1. Sand the defect with 180. You just want to clean it up and provide surface for the gelcoat to bind.
2. Wipe clean with acetone
3. Apply gelcoat putty (no need for color match you won't see it anyway)
4. Sand flush with the rest of the hull

The fiberglass there is thick enough that you won't need to lay any new. Whole repair takes 30 minutes plus hardening time (the longer it hardens the easier the sanding).

If it's left in the water you should put gelcoat on top since the laminate can be penetrated by water and cause problems down the road

It is not paint, it is gel coat- big difference. What is left is porous and will allow water to wick up into the hull. Fix it, even if you just use white epoxy barrier coat for now, don’t use it as is.

What he said. Sand it, cover it with 5200 or epoxy of some sort - go boating.
