The reason boats don't do drifting Deco on the Doria has to do with the international shipping lanes that the Doria is right next to. The strong currents there can carry a drifting Deco station or dive boat across the lanes of the shipping channel in under 2 hours or worse down one of these lanes. This is a major shipping lane. It is not uncommon to have 4 or 5 ships per hour going in each direction. The logistical nightmare of potentially running interference between a floating Deco station and 600' freighters in pea soup fog is void of any common sense. When I was 2nd captain on Doria trips we explained to customers that we had to cross the shipping lanes to get to the Doria from Montauk. A Northerly current would carry a drifting diver back across these same lanes. Do drift Deco at your own peril!
