David Geer's "The Elements of Boat Strength" is
a very good book. It covers a lot of topics
in pretty good detail without requiring the
reader to be a mechanical engineer. It also
contains the scantling rules he uses for
his projects.

Eric Greene Associates "Marine Composites"
is also possibly useful depending on your
purposes.

"Principles of Yacht Design" by Larsson and
Eliasson is a SNAME publication, as is

Harry Benford's "Naval Architecture for Non-Naval
Architects"

and of course, "Introduction to Naval Architecture"
by Tom Gilmer remains the entry-level textbook
at the Naval Academy.

One thing I found useful was a course on "statics"
which I found on the Internet. I've lost the URL,
much to my aggravation on several occassions now,
but it was by a reputable university and it was
a *great*. I wanted to do the "dynamics" course
as well but as i said, i lost the URL and Googling
has turned it up again. sigh.

Note that my goal was to understand what the NavArchs
and the MEs were doing and how they do it on my boat
project. If I were building something I would certainly
go with published scantlings or otherwise do things
that have been approved by a real, card-carrying
Engineer.

I hope this helps.
