I don't recall if I included it in the numbers I ran for you, but don't forget that you need a corrosion allowance on the exposed surface which doesn't factor in to the strength calcs, but will affect your weight / buoyancy numbers.

I have a study that has the numbers somewhere, I just have to look for it. If I remember right it was about 200 lbs negative before anything else so ends up probably 1000+ heavy when you get all the stuff on it. I think the HY-100 was like 800 positive before anything. I want to limit it to no bigger than a 6 feet diameter. My goal is to have a vehical no heavier than 10,000 lbs.
Thanks,

Scott,
I am talking about 516-70, when you say way over, ! ; what does that mean, and can increasing the dia compensate. I thought you were talking about 1,000 meters.  If you decide on 2,000 m then that is another story :-)  Seems your trip to see Karl has given you some things to think about.

Hank,When
you say traditional material are you talking 516 grade 70 or
HY100. If it is 516 grade 70 it becomes way overweight. If
it is HY100 I have the sheets that Sean ran for me. The next
question is do I want to aim for 1000 meters or 2000
meters? Thanks,Scott
Waters
