yarb By hauling the reef-tackles chock-a-block we took the strain from the other earings, and passing the close-reef earing, and knotting the points carefully, we succeeded in setting the sail, close reefed.

reesetee The present meaning (filled to capacity or overloaded) derives from a nautical term. The derivation of chock isn't entirely clear, but the word is thought to have come from chock-full (or "choke-full"), meaning "full to choking." This meaning was later used to name the wedges of wood used to secure moving objects. On sailing ships, a block and tackle pulley system was used to hoist the rigging. The phrase chock-a-block describes what occurs when the system is raised to its fullest extent, i.e., when there is no more rope free and the blocks jam tightly together. Dec 10, 2007
