Stitch-and-Tape Kayak Plans!
O.K., long time coming, here are my latest plans for a Stitch-and-Tape
kayak, (currently not named) once again, copywrited by me, but
available for personal use.

Garmon. Non-commercial use is o.k., however, you may not

Important note: Because the data presented has been
'unfolded' and measured against an abitrary axis, I don't know
what will happen if you scale one of the dimentions up or down
(scaling both equally is o.k.). Probably something unpleasant
(i.e., it will probably 'skew' the proportions, and maybe NOT
in the same directions for each figure).

Whoa! A 3d VRML world version of the kayak!
I spent a couple of days writing a comp prog to convert boat
offsets into flat, 'unfolded' representations of the original
data. That program generated the data from which I produced the
representations you see here(.dxf, .geo) , the 'unfolded' dimentions(text,
postscript), also.
The actual lines of the boat took far longer to design than
the program.

Clearly, the figures are created by transforming the 3d offsets
of the boat into triangles that 'grow' outward from the first.
Then perpendiculars are drawn from a (derived) baseline at intervals
and where they cross the 'unfolded' figure, are measured. These
'.gif' images are much too lowres for anything but examples (I
also cannot guarantee they are correctly proportioned).
What can you do with it? Well, if building a real kayak isn't
your speed, you could output the postscript files to a printer
(scale 'em as you like, but be sure to retain the proportions),
spray mount 'em on cardboard and make your own model! (just a
hint--hot melt glue!)
The postscript files have index #, which refer to measurements
in an .unfold file. This format contains the 'real' data needed
to build a boat (see the readme file for a description).

Wow, what great documentation! (yeeccchhh)
A short Text description of the
boat.
You probably will need a book on Stitch-and-Tape boatbuilding
(check the library) or read a description of the process online
(there are several sources).
