If you repair the fiberglass w/out drying out the wood core, then the wood rot WILL continue to spread untill it eventually rots the entire core...yours sounds like a relatively small area now, so it can be dried before you repair the glass...there's a repair method/product called Git-Rot...everybody has their own opinion about this stuff, but yours is a prime example of its best use...you'll HAVE TO HAVE the boat put away and in the DRY for a long period of time...drill 1/8" holes thru the top glass skin starting close to the center of the rotted area and working out to where your drill bit finds solid wood...w/those holes for ventalation, it will eventually dry out if left in a low humidity atmosphere...blowing a fan across the area constantly will also help...but the Git-Rot product requires DRY wood to work properly and that's gonna take time...Google it up, read the procedure and see if it is for you...
