Test (Routine) Dive
C – “Prepare to dive” – Navigator(/Helmsman) immediately slides down ladder from tower, goes to Echolot for quick sounding then to aft ballast vents. Bridgewatch goes below in following order: Radioman (to negative controls), Helmsman(/Navigator) (to rudder station in control room), Commander last and closes hatch. D – Switches to electrics, then Great Ahead, mans fwd ballast vents, reports “Forward vents ready”. N(/H) – Reports depth under keel, then at aft vents: “aft vents ready, all vents ready”. Marks current position on map. C – Shuts tower hatch, orders “Flood!” D – Opens fwd ballast vents, reports “Forward open”. Sets fwd planes hard down, aft down 5.

R – Blows negative, reports when done “Negative blown”. Mans hydrophone. C – Orders “Go to x meters”. D – Reports depth in 10-meter increments, having established a down angle of 5-8 deg. Levels off 2-5 meters below ordered depth, sets planes fwd up 10, aft up 15 and approaches ordered depth from below. At desired depth: D - Reports “Boat is balanced”. C – Orders “Close vents”. H – Closes fwd vents, reports “Forward closed”. N – Closes aft vents, reports “Aft closed, all vents closed”, inspects for leaks, reports “No leaks in the boat”, reports compressed air level.
