TM 55-607/NAVSEA OP 3221 Rev 2
d. When a ship's structure in the cargo hold (such as a ladder or kingpost) is encased, the sweatboard-to-
sweatboard stowage pattern may be modified to permit tight stowage against the encasement structure. In this case,
stowage would begin in the normal manner at the port and starboard sweatboards and work in toward the center of the
hold. Cargo should also be placed tightly against the encasement structure at this time. The overall stowage then
progresses from both the encasement and sweatboards toward each other. Any void that occurs at the center will be
shored with a full-block structure.
e. Again, it is stressed that the preference of the ship's master is final, and he may require full-block construction for
all voids. If this be the case, construction will vary with the configuration of the unit load and the width of the void, but
the requirement for full blocking, providing bearing surfaces for the full depth of the unit loads bounding the void, must be
satisfied. Figure 8-32 shows a typical full-block structure in the top tier of 750-pound bomb unit loads. Figure 8-33
shows a void between unit loads of a top tier that is in the process of being fully blocked. Construction details for another
