I think the principle is to glass places where water might go through the epoxy layers. In page 6 of building booklet it says "Glass top surface of fitted locker floor. The glass floor will protect the floor from scratching and moisture ingress (as this is a wet locker)" (tiki 30). So I think on the inside of the boat glass is required where water might come to be there for a while.
OTOH it is your boat and the fiberglass will posibly add to the structural strength, but at the cost of more labour, materials and weight. As for me, I'll trust the designer's experience and follow the plans, there's always time to add or modify things once you see how your boat actually sails.
If the fillet is properly sized, and composed of the correct filler materials, it's already stronger than the material being glued together. Adding fiberglass will only increase the final weight, and add additional labor and material costs, for no benefit.
Thanks for the advice. I will not glass them as they are made to spec. The boat I am building is a Tiki 26.
You will not loose speed at all. You'll loose some load capacity.
Whatareas inside are you glassing with 4oz cloth....bilges?
