I think that I will drill the front of the hulls with a 10mm drill then epoxy in a 10mm pvc pipe to run my spinnaker bridels through
Why so big? Only make them as big as they have to be to get the rope through.
When Peter put the holes in the bows of Red Alert (a very light plywood boat) he stood the boat on it's nose and filled the tips up with epoxy filler so they would be a solid and waterproof attachment for the bridle.
