How much lift do you need out of a set of wings? Is there a formula to calculate the amount of lift required for a particular gear configuration? Do you add up the weight of your kit when above water or below when it is almost neutral? I dive square profiles in the North Atlantic (USA). I use double 85 ft3 L.P steels (76 lb. full) or 112 ft3 L.P. steels (98 lb. full) for deeper dives and a neoprene dry suit. I have been taught that I need close to 100 lb. lift capacity out of a set of wings. Yet I see some of you folks jumping off the boat with 50-60 lb. lift wings and your tanks are the same or larger than mine. What am I missing here? Dive safe!
