Well that settles that, the thruhulls in the bow are not cored (under the v-berth and behind the water tank) . Solid fiberglass it looks like.
Pic: (uploaded since attachments don't get through to the list): http://svviolethour.com/?attachment_id=247 Note the innermost layer is the plywood backing plate, next comes some white caulking that it was glued on with, then the hull. This pic is from before I finished cleaning all the white glue off the fiberglass. Not sure if the turquoise blue outer layer is the original gelcoat color, or a barrier coat. I was surprised, but this saves some work. The old transducer was a bear to get out (had to cut it out).
