Rigging Combat Rubber Raiding Craft
SECTION I-RIGGING SINGLE ZODIAC F470U BOAT
DESCRIPTION OF LOAD
2-1. The description of the load rigged in this section is given below.
• Inflated zodiac F470U rubber raiding craft. This boat is rigged on a 75- by 144-inch combat
expendable platform (CEP) with one G-12E cargo parachute. The weight of the boat is 250
pounds. When inflated, the boat is 75 inches wide, 185 inches long and 22 inches high. One or
two 35-horsepower outboard engines that weigh 136 pounds each power the boat shown or one
55 horsepower engine that weighs 215 pounds with a full fuel tank, six paddles weighing a total
of 24 pounds and two sets of air pumps with hoses are parts of each boat’s equipment.
Note. A 40-horsepower engine is the largest that may be used on this boat when the boat is
equipped with the accordion floor. An engine as large as 65-horsepower may be used on this
boat without the accordion floor.
• Accompanying load. An accompanying load weighing at least 650 pounds but no more than
1,170 pounds must be dropped with the boat.
PREPARING THE PLATFORM
2-2. Build a new CEP, or recondition a used one, using the procedures shown in Figures 2-1 through 2-4
and as described below. This platform is used for all the loads in this chapter.
• New platform. When no used CEP is available, build a new platform for this load as shown in
Figures 2-1 through 2-4. Salt-treated lumber is recommended for the platform frame.
• Used platform. When a used CEP is available, inspect and recondition it as described below.
• Inspecting for damaged or missing parts. Check the platform to see that all parts are present.
Inspect each part carefully for damage. When the following conditions exist, the platform is not
suitable for use until it is repaired:
-
Any part is missing.
-
A stringer or spacer block is broken, cracked, split, or severely gouged.
-
A plywood panel is cracked or gouged through at least one ply for a width of 2 inches
or more.
-
A plywood panel is gouged for a length of 12 inches or more.
• Inspecting parts, screws or nails. Check the entire platform for loose stringers, spacer blocks,
and plywood panels. Also, check for loose, missing, damaged, or protruding screws, bolts or
nails. These defects may be corrected as follows:
-
Nail loose parts that are undamaged. Do not nail in original holes or in the grain line
used before. Use screws when possible.
-
Replace loose, damaged, or missing nails, screws, and bolts. Reset or remove and
replace protruding nails, screws, and bolts.
