Ships engaged in alongsidereplenishment at night shall display the required tasklights in accordance with the criteria set forth for dayshapes in paragraph 2.4.6.1.The display of task lights during the approach andwhile alongside often tends to impair conning officers’night vision to the point where safety is endangered.Therefore, if the tactical situation permits, it may be advisablefor the replenishment ship to turn off her tasklights during another ship’s approach, keep them offwhile a carrier is alongside (using the carrier’s lights forthe alongside group), or have replenishing ships turnoff task lights during the approach and while alongside.All ships must be prepared, however, to turn on tasklights (as required by the Rules of the Road) if the replenishmentformation is approached by othershipping.Displayed atthe outboardyardarmPrepBravoAt the dip: Expect to disengage in 15minutes.Close up: Replenishing completed; amdisengaging at final station.Hauled down: All lines clear.BOTH SHIPSWhere best seen: Fuel or explosivesare being transferred.DELIVERY SHIPAt the dip: Have temporarily stoppedsupplying.Close up: Fuel or explosives are beingtransferred.Hauled down: Delivery is completed.RECEIVING SHIPAt the dip: Have temporarily stoppedreceiving.Close up: Fuel or explosives are beingtransferred.Hauled down: Delivery is completed.Figure 2-15.
