I presume you meant hole in fiberglass and not wood. If this is the first time you have had a water leak issue I would not rush to drying the boat out with inspection ports. Drain all the water you can, then weigh the boat. If under 145 lbs, no need to dry out in my opinion. But to fix the leak or hole I would use epoxy and my preferred epoxy is PC-11 which you can buy at Ace or Lowes or HD. It is a two part, thicker epoxy like peanut butter and will work even if laminate is wet. But sand that area first, then apply the PC-11. I use wax paper to smooth the epoxy leaving it in place until the epoxy cures. That way you don't have to sand final surface.
I repaired a split Zuma hull with PC-11 on a Saturday afternoon and was back in the water the next day.

Newbie here. Have been running an old AMF SF for five years or so, all well. After sailing a bit this spring, brought in the boat and it was really heavy. Heard sloshing. Okay have a leak. Did a visual inspection and found a problem on the stern end of the daggerboard slot down at the hull. Some cracking of the fiberglass around the opening and I can stick my pinky in a gap in the wood at the back of the slot. No inspection ports, so I'm going to have to add some to dry it out, right? Have been reading all the #daggerboard topics and getting smarter (I hope), but will it be possible to repair the hole from the outside, without opening the boat? Any other suggestions/pointers? Thanks so much. Jack
