Detailed information

Product detailed description

The sheet block consisted of one large pulley and a second significantly smaller pulley rotated 90 degrees and connected above it. Above the larger pulley, there was a hole in the block for attaching the pulley. This special block was used exclusively at the ends of the yards, primarily on ships from continental Europe.
The block was attached through a hole in the block with the larger pulley facing the yard. A tension rope from the sail one yard higher – called a "sheet rope" – usually for a topsail, ran through the larger pulley. This block was subjected to an exceptionally strong pull exerted by this large sail. A lift rope passed through the smaller, rotated pulley. I recommend looking at a diagram for the attachment and use of the block!
