I'm guessing you don't use a long hose. FYI - as stated earlier, swiming to an anchor line, in current, ascending while looking at your buddy is all easier while on a 7' hose. You don't need to be in a confined space or a silt out to be effective with a long hose. Also most of us throw in a loop on the hose when swiming side by side, thus shortening the distance between divers.novadiver:This is the reason to research a little history on the long hose, In short, the primary long hose is used for ooa divers in no viz. that way the donor diver can feel the ooa diver feeling for his head and be ready to donate gas. second, the long hose is used to bring two divers through a restriction when they cannot swim side by side. as you can see, an ooa diver in good viz can use a short hose to breath from because training dictates that that diver grab your shoulder harness for the ascent. In less your diving with a buddy with seven foot arms the long hose is not needed or you are diving beyond your cert level.
If you get your training from a " fashion show training org." you probably don't know the reasons behind the gear. At that point, your at risk.
Personally speaking in an OOA recreational situation I don't my buddy to have to be right on top of me. If one of us has to blow a bag, then a little distance is a good thing.
