Flipping the Deck and Preparing for Glass


























Now I will explain what all of these photos and videos are and what we had to do to the underside of the deck in order to be able to attach the the two havles.

On the transom we needed to attach some glass plate for where the twin rudders and an outboard engine will attach.  If we were to just attach the rudders and outboard (well, we would not be able to attach the outboard) to the foam the chance of them just breaking right off is extremely high.  This glass plate needed to be glued right to the fiberglass that we already put on.  We had to router out the foam in the area that everything goes and then chiseled and used a hack saw blade to do the rest.

The next series of photos deal with the bulkhead that was installed on the deck.  The designer had initially want to have the bulkhead touch all sides so that you would not be able to get in around it and also had designed it to be 10 mm thick.  Once we flipped the deck over he decided that it needed to be closer to 16 mm thick and instead of touching the port and starboard sides just take it the width of the cockpit sides.  Naturally, now, we had quite of bit of shaping in order to get this all done how he wanted.  In addition to these new designs, we had to still extend the bulkhead to the hull and shape it because when the temporary frames were designed and constructed we did not plan on building the bulkhead directly in the deck.  So we got a piece of foam and thickness-ed it down to 6 mm on the wide belt sander and then attached little triangle pieces on either side to fill in the gaps.  We then coated it in expoy and vacuumed the new pieces to the old bulkhead.  Next, just as we had done on the outside of the deck, we had to install carbon uni strips that will disperse the weight of the mast down to the hull.  We did not need to rebate in the carbon uni like we did last time because this is all on the inside of the boat.  We then calcualted out the correct distance the bulkhead needs to extend to touch the floor on the hull and cut out that shape.

 After we had finished with the glass plate installation and all the work on the bulkhead we were able to glass and vacuum the deck.  The glass was the EDB240 because it is on the inside of the boat, therefore does not need to be as stiff, therefore saving weight because there are fewer glass fibers.
