In sailing, a captain and crew rely heavily on the use of blocks, known to landlubbers as pulleys. The mechanical advantage generated by a block allows an exponentially greater amount of work to be done, especially when sheeting-in (or pulling in) massive sails which can harness enough wind power to pull a multi-ton boat through the water at speed.
Without blocks, a sailor would be holding the full weight of a wind-laden sail in his hands. It would rip his arms off if he didn’t fly off the deck first.
It’s no wonder we were never meant to go through life alone, nor were we designed to work alone. Chose your friends carefully; they’re the best blocks you’ll ever have. ch:
