Exactly my point.
I have a modified resortsub (sportsub II) but how do I
calculate the weight once I close the cabin off, capturing that bubble?
Thanks-

heavy can I go?
Hi Greg,
Which one do you mean ? SportSub No. I or II ?
generally speaking you have to compensate the extra bouyancy with extra wight.
The extra bouyancy is given by the extra volume ( of air in this case) and
considering the salt content.
The extra wight is equal to the extra wight of the displaced water but keep in
mind that the wight of some steel or lead blocks are not the same under water
as on air. (because the displace water themself)
