Re: Need help with fixing this, UPS backed into boat, need details and material list.
Duct tape...

Nooooo! just kidding...
From the looks of it seems mostly cosmetic...I think with a good repair in that area, you should have no worries about ripping the bow off when winching the boat up on the trailer...
Matching the gel coat, that may be a bit more difficult, but not impossible, if you are willing to spend the time on it...
The best approach is to dish out the damaged area about a foot all around...I would work on the upper [cap] section separately from the bottom [hull] section...
If in the procees of grinding away the bad stuff and dishing it out you create a void in the center of the fiberglass, you will have to use an old "hole in the drywall trick"...create a backing for the hole out of cardboard with a string to pull it as tight as possible to the backside of the crack...this is assuming you do
NOT have access to the area being repaired from the inside...this support will become part of the boat after the repair...
Then begin by applying several layers of CSM and 1708, as illustrated below...
Once you get close to the finished surface height, you make a filling/fairing paste out of the resin, or you can finish filling the area with color matched gel coat...
Then repeat on the lower damaged area...
The materials you will need amount to about a gallon of polyester resin with catalyst, a couple of square feet of 1.5 oz. CSM [chopped strand mat], maybe a yard of 1708 biaxial cloth, a pint or so of cabosil/aerosil, and a couple of handfuls of milled fibers...some 40-60 grit sandpaper, an inexpensive 4" angle grinder from Harbor Freight and a couple of 24-36 grit sanding discs for it...a couple of sheets of 80 grit and 120 grit sandpaper, a couple of chip brushes, some acetone, a couple of one quart mixing buckets, respirator, solvent resistant latex type gloves, goggles, some baby powder to keep your skin from itching and a few other odds and ends...
Once you are done with the repairs, then you can get a short section of rub rail plus insert, to finish it off...or if your pockets are deep enough, you could replace the entire rub rail...
BTW, I just want to say, this repair is in no way a substitute for the very real possibility that the rest of the boat may be in need of a full restoration, which if it is, I wouldn't worry about this repair until well after I began the restoration...
Let us know how it goes, and if you have any other questions, feel free...
Best of luck and have fun!
PS- there is a little more to it, but that's the basics...
