Only without the format. Sweet. Thanks Sean. It's going to
take a syntactic buoyancy package to get it right, but it
looks like a decent alternative. A 6 1/2 foot sphere displaces
about a thousand pounds more than the pair of 5 footers.
Pretty close, and might be marginally less expensive. What
would a 39" radius do for depth in the thicknesses you have
already given?</font>
