Re: [PSUBS-MAILIST] launch ramp

I had thought of this in my previous sub ideas, and I felt hat a
two-piece boat trailer would be needed.  You have the trailer and
trailer frame with all the neat stuff on it- axles, brakes, so on.  Then
you have almost like an extension of the trailer, that when packed up is
part of the trailer, but when launching extends from the trailer into
the water, HOLDING the sub.  Very similar to the pontoon boat idea
someone mentioned before.  Actually, it's nearly identical.  The
extension/pontoon dock sits in the water and you launch the sub from
there.  If you need to launch the sub/dock in shallow water, you
pressure up one or more of the pontoons.  If you need to adjust the deck
height, you let air out.  Similar to the water used for sub ballast,
except it's a part of the trailer.  

Sadly the weight of this idea is going to be a lot.  I presume that for
a 10,000 pound sub (22,000 kg), the trailer would weigh around 6,500
pounds (14,300 kg).  All in theory, of course.  I could be wrong.  

What do you guys think?
