1. In order to provide maximum security in transporting troops to United States it is proposed to establish a fixed westbound transport lane to be used throughout year, and to publish this lane in pilot charts, and to request all traffic to keep specially bright lookout in crossing lane and to cross so far as practicable during daylight.
2. Lane proposed will pass through position “A” Latitude 47º 30’ N. Longitude 10º W. thence on great circle to Position “B” Latitude 39º 30’ N. Longitude 47º W. Ships for New York or Delaware after passing “B” steer direct for Position “C” Latitude 39º 50’ N. Longitude 70º W. thence direct for destination. Ships for Chesapeake after passing Position “B” steer direct for Chesapeake.
3. This lane will be primarily for transports bound to New York or ports south. Nothing will prevent transports from following a more southerly route if this becomes desirable.
4. Transports sailing for ports north of New York will follow regular great circle lane from Scillies to destination. Lanes referred to were agreed to in 1913 and are shown on U.S. pilot charts and on Admiralty chart #2058
5. Westbound cargo vessels to follow special transport lane throughout year or more southerly route. Cargo vessels bound for ports north of New York follow same procedure as paragraph 4 if weather permits.
6. All eastbound vessels whether cargo vessels or troop transports to follow procedure recommended in my 9295.
7. Westbound loaded transports to be sailed so as to cross north and south traffic in Bay of Biscay so far as possible during daylight.
8. All troop transports to be fitted with speed light on main truck for use as range light.
9. Transports carrying small amount personnel to follow either special transport lane or procedure of paragraph #4 at discretion. Your 4656 174714 9705
