Fiberglass Repair Help :(

[nymack66]

Starter remove the rub rail and using an angle grinder remove the gel coat from the outside it will expose the damage and post updated pictures including from inside the cuddy it will help a lot.
Also please post or describe the overall condition of the hull including the Deck and Transom
I hate to say it it will be costly. I am still chewing on some thoughts I will post it later. I need time to really think this through.
This is not a repair its a structural reinforcement and needs to done correctly.
You will probably need to make a important decision later base on feedbacks or price quotes replacement hull or repair this?
