With much trepidation about fitting the cockpit seats and sleep platform decking, I've been looking for that 'perfect' method of transferring the curves of the hull to the plywood for the seats and deck. I decided on the tick stick method. I also decided to test it with a sheet of luan before risking a sheet of meranti plywood.
Using foam core for the spiling batten and a simple tick stick, I marked off the shape of the port-side cockpit seat.
Transferring the marks to the luan, the curve (matching the hull) looked WAY off…
I measured, checked those measurements and remeasured. (Interestingly, to me, the while foam-core, reflecting the sky, looks blue in the photo.) Everything checked out so I cut the luan to shape. And… needing only minor tweaking, it fit! Cutting the meranti was, once I made the first cut, anti-climatic.
It fit, too.
This is a major hurdle for me. Yes, I only cut and fit one piece today - but now I know the method works. More importantly, I know I can do it! Tomorrow, the rest of the seats and decking!
