The following conditions will reduce the ratings from those given above. The raft commander must monitor bow freeboard as well as trim to ensure that safe crossing conditions are maintained in the following conditions: a.  Rough, choppy, or turbulent water in current speeds above 4 feet/sec (1.2 meters/sec) will reduce the ratings from those given in the preceding table. b.  Shallow, fast water of less than 6 ft 7 in. (2 m) water depth combined with current speeds above 4 feet/sec (1.2 meters/sec) will reduce the ratings from those given in the preceding table. c.  Accumulations of snow, mud, or ice will reduce the ratings from those given in the preceding table. 2. Raft commander must observe leading edge of raft and decrease speeds or halt operations, as necessary, if continuous water is coming over bow dam or ramp tips. 3. For 4-bay, 5-bay, and 6-bay rafts, ratings are for single or multiple vehicles. 7-bay rafts have separate ratings for single vehicles and multiple vehicles.
