Re: [PSUBS-MAILIST] OSS Show your hands!

[Warren Greenway <opensourcesub@yahoo.com>]

I agree with you. That is what I want to do, carefully
consider the cost. I think that if we do a two-man, it
would be nice to make it an option (change X, Y, Z and
you have two man capacity, at the cost of run time,
etc.)
I'm intrigued by you scooter idea. Can you make a
quick drawing to demonstrate, so I know we are on the
same wave-length? I don't think that forward
visibility is critical for the passenger, only for the
pilot.
