Think that's what its called, where rope goes through a block with pulley wheels to another one?

Im struggling with the block and tackle rigging for Dirty Harry MSW Envoy and since MSW took down their customer gallery, I cant see how others did it. The instructions and plans give not clue how to do it either.

Basically there are two blocks on each lifeboat derrick. Each block has two ropes (I guess would be one continuous one but it goes through each block twice if you get my drift) that pass through it before returning to a bollard on the deck.

Anyone got a diagram of how the blocks would be rigged when one is above the other?

I've attached a pretty poor sketch which may help you follow this explanation.

Start by tying off one end of the cord to the bottom of the top block. Take this through one of the pulleys on the bottom block, back up to the top block, down to the other pulley, back to the top and the tie off on the davit.

Cheers. That helps a lot.
