The temptation to try and imitate Nick Schade's (and other) style finally won, and the initial opening I cut was modified to receive a hybrid invention of mine, somewhat resembling Nick's technique. I'd suggest just cutting the form below from the deck, instead of trying my complicated way. I had no choice: I had already cut the larger hole.

NOTE: Clicking on the image will take you to a high resolution (300 dpi) image of the cockpit, ready to print. It's better to save and print it. On a browser it will look huge (> 3000 pixels wide!). Even then, this drawing is scaled. Use the measures to draw it to size on another paper.

The exact location of the cockpit is a bit difficult. The original (Nick's) design indicates 2.42 metres from the front. I have the impression that 'my' design is a little longer and could justify moving it a few cm to the front (say at 2.38 m). Here's the original location:

	This shows nicely the form of the plywood added to modify the original opening.
		The form received its name from its similarity to a keyhole. It provides for knee support while paddling, and the large opening facilitates entering/exiting.
	I used adhesive paper, marked the outer line to follow. Then I cut 120 5 cm long pieces of wood, about 6 mm thick, 19 mm wide.
		Using fair amounts of patience, sandpaper, and handplaning, I adapted each piece of wood to the inclination. Each one is fixed with hot glue to the deck, and using carpenter's glue to each other.
	To adapt the form, where the strips are above the deck, mark the correct inclination...
		... then cut it and glue it on. Note that, while most are glued to the deck from the inside, in the knee support area, they are just 'sitting' on the deck.
	And a good while later... No too bad, isn't it?
		A side look at the masterwork...
	Ready! Of course, the last ones but be adapted in width to fill correctly the last remaining space.
		After the glue dried, I used a handsaw, with its blade turned 90 degrees, to cut the border evenly. I cut 17 mm above the deck. Though I guessed this value, it seems well inside the margins I found later in the books. Below deck, sand the border to get ir flush with the deck.
	Next the upper border. As a result of the hybrid inlay I invented, the border is a bit more complicated and consists of two different inclinations. This border uses 4 pieces of plywood.
		The aft section is easiest: it's just parallel with the deck. The picture shows the glued border (It's too large. I planned to cut it later).
	The front part is more complicated, as it follow the hollow section inlaid in the opening.
		This is the union between both sections. The tape keeps the point aligned.
	Everybody must help to keep the pressure! 20 litres keep the strip down.
		Glueing alone is not enough for all the forces this border will receive. I prepared a strip of fiberglass, with fibers removed to leave only enough to cover the vertical part.
	The strip in place...
		... and now saturated with epoxy. I should have filleted first - now I know!
	Here's the strip completely installed, and the border ready to receive a first coat of epoxy.
