Load on a block is a combination of the load on the line passing through the block, plus a block-loading factor, which is determined by the angle by which the block turns the sheet . For example, a footblock that turns a sheet 180° will see a load equal to twice the load on the sheet. A deck organizer, which turns a halyard only 30°, will see just 52% of the load on the halyard.
