[PSUBS-MAILIST] Psubs Barge

I built my barge for under 1,000 dollars plus the crane, witch I had laying around.

 Sounds like a lot of $$$
 dollar signs ! I wonder if the subs
 were partially in the water if it might make the barge more
 stable. Brian

 Or even
 if we could just find a couple of nice, big aluminum tubes
 or fiberglass hulls to work with, that would give us a major
 head start on designing the rest of the system. 
 Before we do anything else though, I
 think we should consider weights and sizes. Do we want to be
 able to handle two subs at once, or just one? Or maybe an
 option of one large sub (5000lbs.) or two small subs
 (2500lbs. each)? A sub is a fairly dense item so trying to
 handle two subs at once may present issues with stability
 (i.e. after the first sub has launched and the second sub is
 on one end of the barge, thrown in with a mix of wave
 action... yikes! Launching two subs simultaneously is a
 possible solution but would present its own challenges and
 dangers). 
 I'd
 love to say we'll just build it bigger, but I think
 it's important to keep this project reasonable and road
 trailerable (even if in stages) behind regular tow vehicles
 (and not tractor trailers). 
 Perhaps limiting ourselves to a
 single-vessel barge would be best (and would conform to the
 KISS guidelines), but it would sure be nice to have a
 two-vessel capability to get the most bang for our buck in
 terms of diving per ocean trip. Opinions?

 barge that we could do a make over on.

 Is there any
 kind of used boat we could buy and modify
 it?Thanks,Scott Waters

 Re: [PSUBS-MAILIST] Psubs Barge 

 From a practical point of
  view, if we did build a PSub Launch barge, it would have to
 be fairly simple and follow the KISS principle to get it of
 the drawing board and built by a committee.  I for one
 don't have the time to design a self powered ship.  I
 am thinking a larger version of a typical pontoon boat that
 could be towed by the Boston Whaler.  We would need someone
 like Jon to be able to set up something like a dropbox
 account that anyone could populate with files, drawing,
 sketches, CAD files  etc.  We would have to collectively
 establish the overall capability of the barge ( how many
 psubs, maximum weight of psubs, wench/davit system for
 launch and retrieval, auxiliary systems such as lights). 
 Someone that has a 3-D cad program like Inventor or
 Solidworks would have to agree to take sketches and ideas
 folks come up with and build out 3-D model that we could
 collectively critique and make suggested changes to. 
 Someone would need to do
  the basic
  stability calcs with loaded or
 partially loaded deck.  Some one would need to do some
 research on launch and retrieval systems, such as davits 
 or winches and bring forward a couple of recommendations. 
 Someone that is a welder (like Dan Lance) would need to
 review the construction drawing to make sure welding plan is
 workable.  Someone would have to figure out where you would
 store the barge when not in use.  Some one would need to
 figure out a coating plan for the barge.  Someone would
 have to take on looking at what regulations we would need to
 meet to use this in the Florida Keys.  Someone would have
 to do a material takeoff off construction drawings and
 figure out the cost to build and establish a budget.  If we
 did build a psub barge, we would need to pole the group and
 see how many would be willing to split the cost to fabricate
 based on the estimated cost.  We would need someone to
 agree
  to fabricate the weldments and assembly.  We would need
 to
  figure out where to build it and what it
 would cost to transport it the Keys.  We would have to
 figure out how to register such a barge. Would Psubs own the
 barge or would it make since for Doug to own?  Are there
 any legal liabilities of having such a barge and if so who
 would be liable?  We would need someone that is not
 currently building a psub to agree to be the Barge
 Bulldog!

 Or if someone
 would agree to do all the above, maybe we just pass the hat
 and let them do it.

 What a rig Brian, and a decomp
 chamber to
  boot! 
 I like the idea of a group-designed
 and group-built support ship, my only concern being the
 logistics of coordinating a project of that magnitude.
 I'm sure it could be done well given the proper
 leadership and organization though, especially considering
 the diverse skillset we would share as a team from designing
 to fabrication. And I don't think anyone would complain
 about the benefits of a support barge.
