: i have begun drawing my gillemot(sp) plans from the offst charts int the
: book, and like it.

: in order to do this as cheap as possible, i printed my own graph paper
: 8.5x11(10x10 grid) but need 11x17 paper for the middle section of the
: boat.

You could skip the paper completely and draw right on the wood. This eliminates any problem with having to glue the paper to the wood later.

Do a rough calculation to see how big of a piece of plywood you'll need for any given form (and be a bit generous). Then just mark a baseline on it and use a T square and a ruler to mark the points you get from the table of offsets. when youa re finished you can tap a nail or brad into each point and then bend a very thin strip of wood veneer around those nails to give you the desired curved outline. Mark that line with a pencil, or mist it with a short blast of spray paint. Using the spray paint you get a sharp outline edge and don't risk pushing out on the veneer with your pencil.

Cutting along the marked line gives you your form, and you will be able to draw your waterline, sheer line and such on the wood. You might also want to drill a hole or two for alignment purposes.

People who make symmetrical boats sometimes want duplicate forms as the third from from the front is likely to also be the same as the third form from the back. Rather than redraw each form, the common way to make duplicates would be to simply stack two pieces of plywood and cut them both at the same time.

Hope this helps
