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.

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.

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