fiber glass repair job, where to start?

My situation: boat has been aground many years ago and badly repaired since than resulting in delamination. I have grinded it all away and now have to start laying up new fiber. I know the 12 or 11 to 1 ratio, I know one needs to overlap etc.

However, I do NOT know how to deal with the front of the keel hull joint. This is all fiberglass, the lead keel starts below all this. I attach some pictures. Would welcome an advice!

you really want to be using epoxy with a bit of collodial ,silica mixed in for that repair,then progersively laminate with light weight bi-axial cloth.

I also had a serious problem in the keel of my boat, the previous owner had a stroke and I sold the boat badly repaired, here I leave the link to my blog so you can see ideas, but I think yours is much simpler .
pardon my English ....

Whew, that's a bad one! What Atoll said, use epoxy for this layup. Back grind it further too, especially at the aft end. There are a number of threads here on coating a lead ballast keel. Basically make sure it's clean and dry, and coat it within half an hour of sanding the lead bright. Then while it has wet epoxy on it take a piece of 60 grit wet/dry emery paper and wet sand the resin into the lead. Then glass her up. Don't try to do more than a few plies at a time or the whole wet layup will fall on your head! Been there, you don't want to be that guy...

Re: fiber glass repair job, where to start?

This appears to be a bolt on Keel? If so you need to very carefully inspect the area inside. With that amount of damage you will very likely have to remove the keel to repair the damage, it's likely that you have cracks across the flat bottom area of the keelson area. All that should be put back like new then the keel reattached. As for materials, don't want to start an epoxy versus poly thread but I would put it back with the materials used when it was new. Epoxy will not flex in the future the same way the polyester does causing a hard spot and possible cracking later.
