Brian, now THAT is a cool idea. Involve a
retired submarine crew to train the students or adventure tourists.
Install some nice wide windows so they don't feel totally tin-canned.
Something like the Seaview from Voyage to the Bottom of the Sea.
Remember to install MPEG or a VCD system at
each bunk, complete with varnished interior, plush seating (red velvet,
puleese), a brass reading lamp and great food. Hot showers, of course, and
a decent sized head. I hate small heads.
Remember to install both a droppable keel ballast
system and a chase/rescue boat for insurance reasons.
Have ocean sciences taught onboard along with a
satellite link, laptop stations, and a darkroom for the photographic
purists.
Projection room anyone?
I love it!
Rick

Also if you can leave it in the water rather than taking it in and out that can elevate a lot of wasted time. I like Doug's approach., seem more practical.I don't know if the group has ever kicked this one around at all, I'm sure it has been, but sort of in the same vein as the group designed sub but a large style sub . You know those tall ships where collage kids man the riggings from one port to another and learn about what it was like way back when, suppose some interested folks designed and built a WW2 sub replica like the Pampanito for instance. And then it becomes a floating ( or sinking) school ( income !) and travels from Wasington State all the way around, through the Panama Canal, to the East coast and back and forth. So it is always moving so you really wouldn't have to pay for a birth. Also you would have skeleton experianced crew with the students doing all the work. It would be quite the event as it pulled into port!Brian----- Original Message -----From: Fly DeepSent: Tuesday, September 21, 2004 8:16 AMSubject: Re: [PSUBS-MAILIST] Weeds growing up around Dreams (was submersible speedboat)
I had a long letter written for this topic but I decided to stick to the main reasons. I think that most subs end up as flower pots because of the design. Designing a sub has to be one of the most difficult things a person can do. There is no perfect design and the purpose for each design does not fit well with other purposes. Like helicopters, trucks, and boats. The requirements change as the job evolves. And the personal sub actually needs a support vessel. Lets face it, dropping it in the water of the back of a trailer will work a few times. But you'll get tired of checking out the dock pilings in a short time. The real stuff is out there off the cost by a few miles and down there past the second or third atmosphere. The sub I'm building has a flange in the middle so that a 16 inch center section can be removed for 1 person operations and then be put back when 2 person operations are ! required. I feel that many miss the importance of the out of water wight. Lighter is much , much better. When it comes time to pull the thing out of the water and you only have a 2 or 3 ton crane, things can get very complicated. The motion of the vessel and the sub can get out of hand very quickly, not to mention that wave motions can instill up to 5 G's of force during this operation. It's 4 times harder to keep a 2000 pound sub under control as a 4000 pound sub. This is as many things in physics a Quanitive thing. ( Quanitive spelling wrong, oh well ) Plus the personal on deck need to be good at what they do. Sure you can get a few guys for a Saturday after noon and if your lucky no one will have a finger or a hand removed. But once that sub starts to come out of the water every one needs to know what they are doing. Now we can look at communication while its in the water. Another expense that ! should not be over looked. So for a nice day out on the water we'll need a support vessel, say 50 foot. A crew, 20 bucks an hour for 4 people, it goes on and on. After you get back to the dock you just dropped 4 or 5 hundred dollars in the water. My point is that to just start a design for a submarine and build it for fun turns out to be much more expensive than most understand. And if any one is going to build a sub you should find a niche that that can make money. The same thing happens with home built helicopters, and air planes. They seem like a good idea at the start but once you fly it around for a while, (if you don't die in the proses) the good idea begins to be a money pit and it stops being fun. And then once the fun is gone that person that built the thing finds out that no one wants to buy it. Particularly in the toy helicopter scenario. The poor guy sees this cool toy at the county fair and pays 40 bucks ! for a ride. The guy beside him tells him he's one of the best natural pilots he's ever seen and that he should build one. But by time he's done with construction he'll have 40 thousand dollars in the toy and then he finds out he could have bought an old certified Hughes 300 for about the same money. All in all, I think Dug has the best and in my eyes the only sound reason for building a submarine. He's sharing the experience with his son. And maybe after all is done, the only reason any of us build these submarines is so that we can stand back and say. Wow, is that ever cool, it's done. But,,Maybe if I change this and I think I'll move this over here, and I think that should be bigger and I don't need that and maybe if I take this and turn it around, then it will be......or is it the treasure we know we'll find next season?
