1963 Wooden Alcort Sunfish CHIP 03 Mar 19 New Hull Panels

03 Mar 19:

Metal De Persia bailer screw cap. They seize up enough on their own, without help from a coat of paint. First Gen Sunfish did not have a bailer, that might have been the best tack.


Cross section of a DePersia bailer, bow od boat to right. The knurled cap is supposed to be unscrewed while the boat is underway and let water be pulled out of the cockpit by venturi.


Old hull panels used as patterns. There was extensive checking (flaking) in the plywood. These are the aft sections.


Lined up 2 layers of 1/4 inch marine grade Douglas Fir plywood and used hull panels as a pattern. These are the forward panels.


Cut the ply with a DeWalt jigsaw. Stayed just about 1/8th inch outside the line on the outside edge and we'll plane that down once the panels are fit on the boat. The inner edge we cut to the line.


We beat the rain! For our Northern friends, that green stuff is called grass. 74F today.


Keel strip is rabbeted to cover and protect the edge of the hull panels. We'll make a new one.


The Supervisor flew by to check on things.



2 pieces of 4x8 plywood required to make the 4 bottom panels. Next we need to cut the scarfs to join the panels together. They will be attached with thickened epoxy and silicone bronze ring shank nails.


Put a barrier coat of TotalBoat WetEdge on the interior of the Douglas Fir plywood. That interior face is where any wayward moisture would end up and the open grain needed to be finished to protect against moisture. Used a Mighty Mini roller kit and Redtree Fooler double chip brush to carefully smear the paint around, a flood coat. All supplies available from Jamestown Distributors.


1963 wooden Sunfish had a V shaped coaming, aka the Mustache, cut from mahogany. Attached through the deck with screws at the end. Held together in the middle by a cool bronze bracket made by Wilcox and Crittenden Co, Inc.
