John Gardner's "Dory Book" is the classic reference, available in many
public libraries.

For a simple approach to dory geometry look at the writings of Barend
Migchelsen of Dorval, Quebec. His writings have been serialized at
www.duckworksmagazine.com. The recent stuff is covered by the new fee to
view articles but some of his older stuff can be viewed for free. He also
sells booklets of his dory geometry on his website the address of which I
can't remember.

(I used Barend's geometry as a starting point for the free skiff design
program on my website but had to revert to analytical geometry for some of the
math for a skiff. The transom throws things off. This summer at the beach
I solved the problem of the concave cut along the bottom edge but have not
put it on the WWW as yet.)
