Re: Anhinga...
That is what happens when you draw boats using pencil
contend with of the numerical kind. (Though you can lay out most of
this boat with a framing square. :)) In many instances one can fit the
exact same curve by hand that was used to draw the boat by the
architect.
I don't think I entirely stated things correctly. The numbers I gave
are for the bulkhead, but I also stated they where the boat's side
height, or some such. Of course the bulkhead is undersized by the
thickness of materials applied, the keel timber, and any camber given
to the deck, where the profile view is concerned.
Also when you measure the max max on this boat they don't line up. The
max beam is ahead of this point and the max height is this point and
aft.

Never happened to me before but two of my posts seem to have been
sucked into the void, they appear with BH's original text in them
then drop off.
anywho, here is the most recent one:
I posted a longer reply, I hope it didn't end up in some unrelated
group!
The max side height is 3,5,4
The half beam is 2,5,2.
These are measured at Station "D", which is 0,9,1 aft of the 11' mark
on the expanded panel, or roughly the 7.25" point on the drawings at
3/4"'1' scale.
When I made Eeek! I remember there being some oddity like the max
height and beam didn't coincide.
The bow is 2,6,0
The sail is 140 square feet, and the center is pretty much over the
center of the board. The spar is a asymetric hollow mast section.
There is a lightly hand drawn lug design on my set, that has 144 area
at the forward edge of the board, seems to share the same spar. OK,
turns out that lightly drawn outline was by Bolger himself.
The SB rig had slightly less than 140 split between two sails.
