Re: [PSUBS-MAILIST] Sitting High

["Patrick" <pat_man_ta@hotmail.com>]

I had thought about inflatibles but I want to keep my design as streamlined as possible.

Surface speed is a consideration but also, I really wanted the sub to be big, buoyant and stable enough

to have a 'deck' that could be walked on. I seem to want the best of all worlds here {:\

 

I too would like to build a 40 footer but I think I'm going to start a bit smaller for my first venture.

Something trailer-able.

Patrick....I have often thought of ways to make a sub sit higher in the water when at surface.

You need to overcome the weight of the craft with larger ballast tanks. Remember that anything above the water weighs more than it does submerged. I have been toying with the idea of adding inflatable ballast to my sub to get more lift while at the surface. Something along the lines of a big "tractor" innertube that would flatten out when submerged, and sit behind a spring loaded fairing just below the main ballast tanks.

There is a man making a submersible boat that looks like a surface craft, can go fast, and has a stateroom, galley, etc.

I can't remember the name, but it is on the web.

Seems to me it was about 40 feet long and cost about 2 mil.

They were about to go into production I think.

If I see it again, I'll post a link.
