Re: fiberglass delamination?
Getting worse isn't the problem. If I'm looking at it correctly there's chunk of fiberglass hanging away from the hull, this means if the boat has been used since the damage was done it will have filled that side of the boat with water. The longer it's been that way, the more likely it is to have waterlogged foam and rotten wood.
The glass portion can be fixed fairly easily, the wet foam and/or rotten wood is a much bigger project.
