Re: Anyone know how main boat booms on WW1 Brit Battleships were swung over the side?
The crew could apply winch power to the lines to move the boom with boat attached and, of course, to raise/lower it.
"a" Manpower is questionable. The boats being moved are quite large as is the boom itself! "b" requires considerable size lines to be rigged to some point on the boom. When in the "centered" position, there is not enough room to position enough men to swing the boom unless there is some sort of capstan or "pulley array" in the vicinity. "c" where is the winch located. Have not seen any "candidates" on ship plans for WW1 Brit BB's. hence my question.
About the only options available are something like this:
a. Boom is moved by manpower.
b. Boom is moved by manpower pulling on lines.
c. Boom is moved by lines attached, power by winch.
The boom is mounted off a leg of a tripod mast. The "lifting" pulleys and lines are clear but how those large booms were swung out over the side is not. We see cranes on American dreadnoughts with machinery on a platform that both lifts and swings the boom. The brits had no such platform and the lifting winches seem to have been on the deck. Anyone know how the boom was swung?
