Abstract

The boom is supported by a hoisting tackle running part (2) and secured to an eye plate (1) at its head. A separate tackle (4a, 4b) goes to a winch. The running part of the hoisting tackle is divided at the boom head, one part (2a) going via a fixed block on deck (3) abreast the foot of the boom to the guy-eye plate at the boom head, the other (2b) going via the mast to the winch as normally. This arrangement eliminates the need for a deadweight to prevent the boom swining uncontrollably when there is no load to steady it.
