Hank,
Where is your source for HY-100?
Thanks,Scott Waters

Thank you Sean,Good to know it can dive even at high tide ;-)  Now I can find out  if it is more cost effective to use HY-100 and less foam or 516-70 and lots of foam.Hank

    Finally, because I thought you might end up asking for it, here
      is the sphere using 1.5" thick HY-100, where 1-13/32" is
      considered in the working depth calculation, and the remaining
      3/32" is the applied corrosion allowance which does not contribute
      to working depth, but does affect the final weight and buoyancy
      characteristics.  The mean and outer diameter indicators do not
      update after the corrosion allowance is applied, but these
      dimensions would be 43.5" and 45" respectively.  In this
      iteration, you need about 770 lbs of supplemental buoyancy, but
      you can put her deep in the mud beside Titanic at high tide
      without issue.
