Hull Damage - Lasting / permanent effects?

Hello!

I store my boat on its trailer in indoor, heated storage at the same marina in which I slip during summer. They haul it out, store it, splash it in summer and I enjoy, all in all, a pretty slick deal.

This spring however, I noticed a relatively large gash in the hull. it's about 3" high by 1.5" wide and its completely through the clear coat, through the fiberglass and into the hull.

luckily, like any proud parent, I obsessively take pictures of my boat. I had photos of the boat after I manually buffed, polished and waxed (multiple times) every inch of the hull by hand in winter storage (no hull damage featured in photos) and photos of the first day she sat in the water this season (hull damage featured in photo). After showing the marina, they told me they would repair the damage at no cost to me, without argue. Much appreciated.

the question: I neglected to notice this damage until about a month after it's been sitting in the slip. It's been raining and etc rather hard for this past month. Will the exposure of water to the inner hull material (core?)cause hull rot or any issues with the fiberglass now that it's had a month to get rained on and allow water to be absorbed?

Sorry, I posted a link to my Photobucket to try saving the forum's storage and bandwidth. Attached is a photo of the damage I took after I noticed it. It's from the finger pier next to me, with my cellphone, so I apologize for the quality.

A properly performed gel coat repair prevent any lasting effects. The technician should actually grind down into the laminate and build back up with some resin and matt, sand that down, build up with thickened gel coat, sand that down, and finally apply the final finish coat color matched to the surrounding area. Assuming it is done right you will never know the difference and no long term ill effects.

Since the damage is well above the waterline, the inner fiberglass cloth should still be dry. I would expect you can sand it smooth and feather it out, wipe it with acetone and then apply some tinted gelcoat to repair. Should be a simple repair for a professional.

I was expecting far, far worse! That is minor dock rash. Its a very easy repair and zero chance of any lasting problems.
