First Mistake
Right now I am working on cutting the notches for the battens the run lenthwise along the bottom of the boat and gives strength. Also the plywood planking attaches to the battens. Unlike the transom which is notced just for the battens width and depth the frames have quarter moon shapes cut out on the uphill side of the batten notch. These allow any water that is in the bottom of the boat to flow through each frame along the battens and to the rear of the boat where it can then be drained. Forward movement of the boat simply causes the water to move aft but without these notches along the batten the frames would not allow any water to flow past them. Since I plan to water ski behind this boat I plan to drip water all over when I climb back on board.
Also here is a picture of the Poxy Grip epoxy, bronze screws, bronze ring shaft nails and hot dipped galvenized bolts that are used to build the Zip. Bronze hardware is used due to its resistance to corrosion but they sure arent cheap.
At this point I have spent around 40 hours working on the boat and have spent around 5-600 dollars. I keep a to the dollar and to the hour log of the cost/time invested and it will be interesting to add up at the completion of the project.
