Centercase

The centercase is the hole in the boat where the centerboard and keel go through. This gives the boat lateral resistance as well as a type of anchor or pivot point against the wind when sailing. This was made by wrapping several layers of fiberglass around a wooden jig that was made. We then had to cut holes in both the deck and the hull that would fit it. we decided that it would be considerably easier to attach the centercase to the hull first and then after the deck was finished and flipped we would then attach the centercase to the deck after we had it in place and attached it to the hull. We attached the centercase to the hull by finding the correct vertical height as well as centering it in the boat and making sure it was plumb as well, then cove and glass. We doubled the strips of glass and staggered them by 20mm to make it stronger because clovegro told us on several occassions that there is nothing worse than trying to fix a broken centercase. It was glass into the hull and the forward part of the girder. It is aft of the station 7 bulkhead by 150 mm or something so the extra part of the girder that we cut off is going to be installed between the centercase and the bulkhead for additional support. Later we are going to attach some cones to the outside of the centercase which is for the rig that will raise up and down the centerboard because this is a trailer-able boat.
