Subject: Re: [PSUBS-MAILIST] Stepped sail
design .....opinions?
The pressure on the domes will react in the same way, regardless of the
angle. The large flat area on the sail top on the other hand? Is
that something you are planning to use ?

So
Joe Perkel and I have been having a thorough discussion.....which
I've
enjoyed the exchange.
I have some questions about the image
that is attached. (Sorry....hated to
kill the bandwidth, but didn't know
how to le the image be accessible.)
Does the image have a chance to
be successful?
Will the angled mounting of the dome hatches cause any
structural weakness
(other than the acrylic dome itself)?
I know
anyone who answers is doing so with the best intentions. I know that
only
real life testing is the only way to know for sure.
My design is only
for a depth of 250 ft max.
Also understand.....the drawing is a
preliminary......just drawn up to
discuss the possible flaws of the
idea.
