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

If you call ABS they will be able to answer that question.

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.
