Bummer
 

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?

I'm certainly no expert, but it does look structural and I'm pretty sure the 5200 won't hold up to the stress for very long, if at all...

5200 has been great so far. It definitely isn't the nicest repair job but it works. That part of the bow flare is so far up that it isn't stressed too much and the damage hasn't spread any farther than it was. I am going to give it a summer and see what happens, I have a hard time spending a couple hundred bucks to get that spot fixed when I can get an entire new hull for around a grand.
