NOTE
Preparations for being towed should be started as soon as possible after casualty
which disabled the LCU requiring a tow.
Most vessels carry abard an emergency tow wire commonly known as an
o
"insurance cable." This insurance cable is employed for taking a disabled vessel
into tow.
The specific method and length of tow hausers used for towing will depend on
several factors such as protected waters or open waters, weather conditions,
distance to be towed and type of equipment on board the vessel.
The LCU towing bridle assembly will be used for rigging to be towed in protected
waters. The most forward bitts and chocks on the forecastle are used for rigging
the LCU for tow.
The tow bridle can be assembled on either the starboard or port side. Instructions
are given for the starboard side.
(1) Place the FISHPLATE (7, FIGURE 2-260) on the starboard forecastle between the CHOCK (6) and
BITT (9).
(2) Place the eye of the BRIDLE LEG (5) on the starboard side on the forward post of the BITT (9).
Lead the bite around the outboard side of the aft post of the BITT (9), through the CHOCK (6) and
back to the starboard aft SHACKLE (8) on the FISHPLATE (7).
