Setting a Code 0 sail requires a particularly high halyard or luff tension, which often overloads standard halyard sheaves and stoppers. A 2:1 tackle should therefore be installed at the masthead with a special halyard eye and a block at the top swivel.
Note: The pad will now be delivered in black.
