not Bolger, but in the spirit of

Dear Group,
Today, I picked up a copy of David Gerr's book, "The Nature of
Boats". International Marine. It is loaded with discussions on
ballast placement, floatation options and positioning, hull design,
rigs. And, there is also a chapter on boat tarps and building home
made cradles.
This seems to be of great interest to a boatbuilding group.

Happy Building.
