NOTE: If able to position the 40ft PB further forward in the C-17 step 3i may be omitted and the trailer will be restrained on the level cargo floor.

4. Restraint Requirements: Restrain boat and trailer to the aircraft separately. The 40ft PB is equipped with six (6) tiedown provisions (three each side) all rated for 25,000 lbs in each direction. The trailer is equipped with ten (10) tiedown provisions (five each side) all rated for 9,120 lbs in all directions. See Figure 3 for tiedown provision locations. Restraint may be applied to axles up to the axle ratings in longitudinal and lateral directions as listed in the Item Description paragraph. Do not apply more than 50% of required restraint to vehicle/trailer axles for longitudinal and lateral directions.

Spring mounted axles provide zero vertical restraint. The 40ft PB and all accompanying cargo must be restrained to meet air transport requirements of 3G forward, 1.5G aft and lateral, and 2G up. In addition, stored or installed equipment must meet these requirements and be capable of withstanding a 4.5G down load.
