jbichsel:That much lift is so that when you want to surface, you can max inflate your BC/BPW at depth and you will totally clear the water upon surfacing. If your trajectory is correct, you will land feet first on the boat deck or shoot directly into the waiting med-evac helicopter.

this certification thing it a worry though - the local (NSW/australia) state govt is looking at introducing a similar thing as a funds grab, kind of like a fishing license (rather than a safety certification/driving license).
funny though - it will probably cost them much more to administer & enforce than they'll get in revenue
