Re: [PSUBS-MAILIST] I Disagree Rick



Now that borders on the erotic.  A dome view at 900 feet?
Oooohhhhhhhhhhhhh.

I'm aiming for something a little less abitious with mine.  I've had my eye
on the Perry boats for decades.

I'm striving for a canopy view using an aircraft style construction (with
much thicker plexiglass). Despite being ambient (dry) there is still wave
action to consider (momentary sudden increases in pressure)  Up here in the
Straight of Georgia we get 12 footers.  Not to mention an over pressure
valve malfunction, sudden dives where the compensating regs can't keep up,
collisions, etc.

My heart went out to you when I saw that bare interior of your sub.  Where
do you start . . .  There's something about looking at someone else's design
and completing it that gives me the shakes.  My own sub, no problem.  My
design.

Well, one step at a time.

BTW, how do you plan on testing your hull strength?

Rick

ps: how long have you been on this chat line?  I remember you from a few
years ago.  Nice to "see" you again.
