 Alan, I have a new plan, and I don't mind experimenting.  I find it enjoyable to mess with this stuff.   The buoyancy tanks do counter the weight of the sphere.  Hank

 Hi Hank,yes I remember they are carbon fibre & I believe you are going topressurise them to something like 1500psi. But what I thought was thatthe 1000lb net buoyancy was to counteract the negative buoyancy ofthe pressure hull. So thought they would be up front so you don't nosedive. Those floats look good. Alan

 Alan, the Natural Gas Tanks are carbon fibre no steel, and they are for buoyancy.  Each tank gives me aprox 500 lbs buoyancy NET.I just scored a yellow plastic dock from a friend that is about 8 feet by 8 feet for my next attempt.Hank

 Hank, yep you are right about the challenges of making it look sleekwith that configuration. You definitely have to protect those propanetanks, as if they were hit with a stone in transit any dents could makeyou nervous. Maybe you could have frame protection for the bottom ofthe main ballast tanks to half way up as it is not as critical as the top half.Also maybe transition to the curve of the propane tanks, but that wouldmean a fibreglass shell.Hope you don't mind all these questions, but I thought you put the propanetanks on to counteract the negative buoyancy of the pressure hull, that'swhy I assumed you would be diving on an angle with their placement.Alan

 Now you can see why it is difficult to make a sleek round bodyHank

 Thanks Hank,I have saved the images as you are building so often I get confused!So with the propane tanks at the back you will be diving at an angle!( intentionally)?Alan

 Alan, here is a picture of the sub with all the tanks on.  The square tanks up front are mbt the middle aft tank is a mbt and the back two tanks are carbon fibre buoyancy tanks.  This picture is from my mbt test proving the amazing stability.Hank
