Grinder (sailing position)

A grinder is a crew member on a yacht whose duties include operating manual winches (called "coffee grinders") that raise and trim the sails and move the boom. It is a physically demanding role with a significant impact on a racing yacht''s overall performance. The AC50 class yachts used in the America''s Cup competition have four positions (on each side) for grinders.

A Review of the Modeling of High Pressure Grinding Rolls

Austin et al. (1993, 1995) showed that the specific grinding pressure has an inverse effect on the specific throughput. Depending on the specific grinding pressure and the compressibility of the ore bed, the operating gap takes on a value of its own.
