Sheeting

The sides were sheeted with three layers of marine grade ply. First layer of 6mm at right angles to the frame with joints aligned by securing small blocks to pull the sheets at the joints.
First layer completed, second layer started (starboard side).
The next two layers of 4mm at opposing 45 degree angle fully glued and heavily secured until glue dried. all securing screws were removed after drying.
The center board case now needed to be constructed and fitted before the bottom could be sheeted.
Bottom sheeting started and ready for center board case to be fitted.

The bottom was sheeted with first layer 12mm ply at right angle followed by two layers 9mm ply at 45 degree secured as per side sheeting.

The bow was finished with three 12mm layers of oregon timber and shaped to a finish.
Bow trim fitted.
The chines and corners were then rounded and shaped to finish and the sheeting sanded and finished.

As this boat was having an small diesel inboard sail drive motor fitted a skeg was constructed to protect the engine leg.
Hull finished and skeg fitted with cut out to ensure engine leg fits.
With all the sheeting finished the hull was ready for glassing. Before the glassing was done the center board was test fitted to ensure clearances.

Frame construction continues.

The side battens were now to be fitted along with knee brace to bow.
The knee brace was laminated with two layers of hardwood placed with at 90 degrees to each other side by side and glued. final shaping was done by trial and error and the knee glued and secured in place with brass screws. The cheeks were later built up to make it a sold block between the sheeting to eliminate spaces for better waterproofing and strength in the bow.


The side frame battens were laminated from 2 layers of 20 mm hoop pine again laminated in situ for maximum strength. The positions of the battens were taken from the plans to suit the fit out locations of the seats, bunks and shelving. They were butted into the the stern with a cleat fitted to secure both together and stop housed into the bow stem. The battens were then shaped to fit the bulk head sides so sheeting would sit neatly for maximum support and bond to the frame.

The frames were now checked for completion and satisfactory lines and all readied for sheeting.
