First off, I'm pretty amazed at how well that image came accross.
I find it interesting that you are proposing the oposite of what I was thinking. I was thinking reinforce the center and you are thinking reinforce the ends.

: What is the seat location ( back of seat), the exact location of the 7 forms?
The seat is pretty close the the center, which makes using forms 4 (closest to the center) and 5 quite apealing, since the seat can be high enough to prevent any issues with the forms rubbing agains me. The additional form would be nice to attach the seat to.

: This is a very short and fairly tall boat, so 4 cross sections should be
: adequate.
Short yes, but is 10 inches realy all that tall? I was originally thinking 3, so five (or four) seems a good number.

: The drawings I've seen show a rounded hull, so 3 X 1" chines per side would
: allow you to approximate the shape,
I was thinking 2 full length and a third partial would work too, but I'll wait till actually building it to decide upon 2.5 vs 3.

: I see section 3 just aft of the seat
So number five on the picture
: ( at approximately 7ft ?)
7.083 ft, dang your good
: and section 2 located at or just forward of your footrest location, approximately 4' forward of section 3
That would be number 2 at 4 ft 5 inches in front of "3"
: A fifth cross section could be used at the boats center, but I don't think it's required.
It might make sense as noted above

: If you lash / epoxy all joints, strength and rigidity will be very good.
: (see link below). The strip version isn't flexible, so the SOF version need
: not be either. Weight for this SOF should be about 20 lbs.
Good point, but my abilities allow for lashing and pegging. I have yet to feel my traditional greenlander flex, so I'm not concerned about the flex involving lashing without glue.

So we can seem to aggree on numbers 1, 2, possibly 4, 5 but then 6 or 7? 7 would make sence since it is the equivelent of 1, but 6 would allow me more material to encourage the shape of the boat. Does it matter that the forms be symetrical?
Thanks a whole lot.
