pendulum. This is the most critical 
point in the operation. The operator 
must learn to keep the winch lever 
in the brake position when the BT 
is swinging away from the boom, 
to take in wire under power only 
when the BT is swinging toward the 
boom, and to move the lever from 
one position to the other without 
allowing the wire to pay out in 
the neutral position. If the wire is 
taken in while the BT is swinging 
away from the boom, it will invari- 
ably continue its swing into a full 
circle, wrapping the wire around 
the boom. If it is apparent that the 
BT may be in danger of wrapping 
around the boom, shift to neutral, 
allow the BT to drop into the water, 
and begin the recovery over again. 
With a little patience, the BT can 
be safely brought to within two or 
three feet of the towing block. The 
winch motor should be turned off 
at this point, eliminating the pos- 
sibility of accidentally jamming the 
BT against the towing block. 
The BT can then be brought aboard 
in various ways, depending on how 
the boom is rigged. Two men can 
pull in with a boat hook — one man 
on the boat hook and one to give 
the necessary slack with the winch 
lever. If the boom tops up, the BT 
can be brought aboard by one man 
hauling in on the topping lift. Sim- 
ilarly, if the boom swings horizon- 
tally, the BT can be brought aboard 
by casting off on the after guy and 
swinging the boom in with the for- 
ward guy.
