 TB 55-1900-232-10
Stop off the hawser along one side of the towing ship. The towing ship selects the side and speed for passing and
signals them to the receiving ship well in advance of passing the tow. The receiving ship steams into the wind alongside
the towing ship.
The receiving ship signals and sends a messenger when she is ready to receive the tow. The towing ship receives the
messenger and secures it to the hawser. The receiving ship hauls the messenger and hawser through its towing chock.
The towing ship frees the hawser, and the receiving ship hauls it away. See Figure 3-6.
4-2.4.2 Capsized Target.
WARNING
Always remain with a target sled until it is recovered or righted and towed to port; it becomes a hazard to
navigation if it is left to drift.
A capsized target must be righted immediately because it cannot be towed capsized at any speed. Safety precautions
must be strictly observed because of the hazards of recovery work. In case the target does capsize, the towing ship
should heave in slowly. The ship may be required to back slowly while heaving in, being careful not to foul the towline in
the propellers or rudder. Another method is to reverse course and place the ship alongside the target. Either method is
dependent upon weather conditions. Prior to getting underway, the target should have been prepared for righting by
attaching a wire strap to the pipe framework at the apex of the target. Once the capsized sled is alongside, this strap is
then led between the ship and the target and attached to the towing ship's boom, or to a fairlead through the quarter
rollers or chock, so as to enable approximately 20 feet to be heaved in (approximate depth of the target below the water).
When heaving in, this attachment will allow the target to rotate away from the ship and will minimize damage to the
target. Upon righting the target, it must be inspected to ensure that no damage has resulted, and that it is fit for tow. If
unfit, the target should be brought aboard. A second method for righting a capsized Williams Target Sled is to pre-rig it
for a recovery operation prior to towing. A recovery pendant can be made from 60 feet of line. One end of the towline is
attached to the middle of the pipe framework at the apex of the target. The remainder of the line is coiled and secured
with small stuff to one of the pipe frames near the trailing edge of one of the catamaran floats. The bitter end of the line
is tied with a bowline onto the float. Prior to streaming the target, the line and float are released to stream aft of the tow.
If the sled capsizes, the ship is maneuvered alongside the sled, and the float and recovery line are brought aboard the
ship. By leading the recovery line over the caprail to a capstan and heaving in, the sled can be made to rotate to an
upright position in a motion that carries the target away from the hull of the ship. See Figure 4-1.
4-2.5 TARGET TOWING PRECAUTIONS. Take the following precautions when towing a target:
a. Avoid surges.
b. Maintain a steady course, avoiding tight turns.
c. Ensure that the target's stern and side lights are lit at night.
d. Do not tow the Williams Target Sled at speeds in excess of those authorized by Fleet directives.
e. Do not tow a capsized Williams Target Sled.
f. Alter course gradually with a target under tow in order not to capsize the sled.
g. Approach the target with caution. The shallow draft of the target sled causes considerable pitching and rolling at slow
speeds or when drifting
