With at least some lines dealing with displacement (ie non planning)
powerboats in plywood (classical, not stich and glue) , length 30'.

subsidary question :
Does "Guide for building and classing Motor Pleasure Yachts" from ABS deals
with above powerboats ? Or other regulations 'Lloyds ???)

Thanks for using your time to answer.

Two books I would recommend are Elements of Boat Strength by David Gerr
and Principles of Yacht Design by Lars Larsson and Rolf Eliasson.
Principles is by far the more complete and technical book but you better
be strong on math and not "metrically challanged" like me. Elements
is a bit more understandable and provides formulas in English and metric.

Hmm, serioulsy, if you really are mathematically challenged you should
maybe stay away from structural engineering or any other engineering
for that matter.

If you call ABS they will be able to answer that question. I think the
bigger questions is do you have an engineering background?
ABS requires you to know how to calculate section modulus, know
the mechanical properties of your materials, and generally
have an engineering knowledge of structures.

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.

Not everybody live in US. Not so easy to call ABS when you can barely write,
but no speak english. I can understand a slowly oxford english, but a fast
texan (or australian to change country) is far beyond my abilities.

I think the
bigger questions is do you have an engineering background?

Yes.

ABS requires you to know how to calculate section modulus, know
the mechanical properties of your materials, and generally
have an engineering knowledge of structures.


Not a problem. My real problem is to determine the forces that will be
exerced on the hull. In mathematical conditions, I can do some things. But
real life sometimes differs from mathematics.

That's OK. The fast Texans aren't telling the truth anyway.
