Re: [PSUBS-MAILIST] Dumb Question



Hi Stuart,
Thanks to Archimede, to achieve neutral buoyancy and dive, the weight of the sub must equal the volume of the water it displaces. The weight does not change, the displacement does when the ballasts are flooded or dry
Not only a submarine is a vehicle but is also a life support system, there is a long way to go before you can build one.
My recommendation would be
 1) should you review ALL psubs archives and links because you will not find your answears on how to build a sub in a few emails.
2) Take a scuba course to get the basics.
3) Organize your work in 4 topics: Hull, propulsion / energy, life support, ballasting and air system.
4) and may be should you start with a wet sub, easier and safer.
good luck

Well I guest that Idea got shot down. so if I were to find a hull of some short how do I figurer out how much it needs to weight. I checked out some web sites and they had nothing. So I tried the volume it holds times the weight of water and it came out extremely high is this equation right or am I just stupid or is my sub too big because I see must of these subs weight 1500lbs. If some one could answered this I would appreciate it.

P.S. thanks for not letting me fumigate my self.
