Ok, how about "unpredictable". Sure, you can make reasonable estimates.
Then some guy with big eyes and small brain decides to set a new air speed
record off the top of a wave, only to slam into a BIG wave right after. If
you could guarantee prudent use, you might be able to better estimate loads.

Unknown forces?
Like ESP or telekinesis or "may the force be with you"?

Sorry, I just couldn't resist :-)

But also, there are no such unknown forces IMHO.

not surviving etc). If I were you, I'd go ahead and buy the books that
apply, read them, then decide how far you want to take it...the training
and
education or the design work itself. Armchair sports or playing the
game.

Right and if you feel intimidated by the math and physics you'd better
stay away from it.

Go to http://www.multihulls.org/boats/scarlatti/scmain.htm for something
completely different. Please visit the "Technical" section (link at the
bottom) for a very incomplete discussion. Material on structural
engineering will be added as time permits.
