I found a web site giving the order of reeving two 3part blocks together. The illustration shows the blocks turned 90 degrees to each other with the first hauling line beginning in the center of the top block.
Yet on a local schooner they have the blocks axis's parallel and the old salt who reeved them insists he did it correctly dispite the first hauling line beginning at the end of the top sheave.
Is there more than one 'correct' way to reeve these blocks?.
