Fiberglassing the amas (3)
Four hours between last night and this morning to fiberglass the deck of the first ama. Here's a pic of the (tedious) preparation of the surface with the rotoorbital sander and 120 grit.
The fiberglass (160 g/sq.m.) was then cut to size and laminated on the deck using about 500 g of epoxy. The two large aka bearings will be fiberglassed later because we had to fill several screw holes.
This morning we checked that everything was ok, cut away the useless fiberglass from the deck porthole opening, and removed the rough edges of the fiberglass using a Surform and a sanding pad.
Total work time to date: 445 hours.

Fiberglassing the amas (2)
We had to skip the last two week ends due to personal commitments, the last one being my son Giovanni's graduation cerimony at the University of Glasgow.
Anyway, this moring we worked two hours fiberglassing the other side of the starboard ama, using the same approach that we used before. Her's a pic of the fiberglass being draped on the hull side
We then cut it to size and laminated it using about 600 cc of resin and a roller.
Next step will be fiberglassing the ama deck. Last week Cinzia worked about one hour to prepare the hull for today.
Total work time to date: 441 hours
