JT,
you can have at it, I will have look through the list and then do that horrible thing called math and come up with the right answer. Lance from what I saw about the PSI's you were pretty on the spot when it came to blowing the tanks dry and that is a damned good thing to know especially today with the boats that are still in the water because there are a few aparently with their sea chest's and other tanks still open to sea water, that way when you start putting air pressure to the tank you know how far you can go without hurting the boat at all.. Granted on Torsk we only have our compressor running at around 125PSI and we do have two larger ones topside that are rated at roughly 175PSI each that have yet to be plumbed into the air banks and have the power run to them. Good job with the numbers on both the PSI and the amount of variable ballast that can be brought onboard as needed, tonight I will set down and figure the answer out unless someone else would like to confirm Lance's numbers and I will be more then happy to accept that.
