The paperbound edition was last published in 1990, a reprint of this 1953 classic. Smith writes in a 50's style, so you think you may have tuned into an episode of Leave It To Beaver if the Beave had built a boat. Because the gaff rig was still popular in 1953, this books contains some details of rigging. But much of it is dated also, as most of us won't be using hemp rope. Like Knowing the Ropes, above, this book is very interesting, and much for the novice to consider.
T hat's it for now.
As I find more links and sources, I'll add them. Be sure to check my Detail Pages for updates if you are building a boat using a gaff rig.
