Help. Hull repair from the outside...how many layers of glass?

[Tiny]

Over the years our boat shifted further forward on the trailer (float-on with the aluminum hoop). Eventually that led to too much weight on the front guide/crossmember which damaged the hull. Our never leaky boat began getting some water in it. I filled it up at home and water came out just at the support and I cold see the damage. Anyhow, I ground it down to the glass. Two questions.

Have I taken the repair out to the port and starboard far enough? How about fore and aft?

How many layers of 1708 would you use? Whould you use something else?

I'll be using epoxy.


PS. This is father franks old boat! We've got a lot of use out of it. It's really only damaged by the keelson as far as I can tell. I believe water was leaking in the keelson and out the back into the bilge. We've never hit anything.
