The last 4 feet of bottom at the bow is what Martha and I call the "nose cone".
Four feet from the bow, the bottom "V" has a 30 degree angle.
At the bow (the stem), it is vertical, i.e. flush with the stem.
Thus the plane of the bottom rotates 60 degrees in 4 feet. This can't be done with
plywood, even with 1/4", much less the 3/4" we are using for the bottom.
We have tried different materials and methods and may have hit on the one we will use.
We'll know in May or June of 2012.

Plywood would not make the bend.	110911_0847m.jpg Edna Bay, BC - 2011 Making a twisted surface with epoxyed fiberglass cloth layed over stretched strings.

110917_0881m.jpg Edna Bay, BC - 2011 We abandoned this approach because it would have required too much (dear) epoxy to build it up to 3/4". Also, providing an adequate gluing base would be difficult.	110930_0004m.jpg Edna Bay, BC - 2011 We tried cutting grooves half way through 3/4" ply. No luck. It doesn't take the right shape.	110930_0001m.jpg Edna Bay, BC - 2011 We will probably use this approach for half the nose cone. The sticks will be screwed and glued at the ends and to one another, then ground smooth and trimmed.
