The Harken Hexratchet Mainsheet Block grips loaded sheets and allow easing with total control.  Trims fast under low and high loads.  The racthets feature Hardkote-anodized, Teflon-impregnated eight-side sheaves --- these are machined from solid aluminum for strength and resistance to corrosion.  Contains free-rolling Delrin ball bearings.

The Sheave and sideplates are UV-stabilized with carbon-black additive protection.  Strong stainless steel straps reinforce the blocks.  Use with the Harken 010 Mainsheet Rachet Base to allow the block to stand and swivel.

Basically the world standard for mainsheet handling. Used on PocketShip, and any other CLC boat with a large mainsail.  The essential value is that it keeps your hand from getting tired, yet it isn't dangerous like cleating the mainsheet would be.  A small amount of pressure causes the sheet to jam in the block, taking the pressure off your hand, but if you ease up on pressure, the mainsheet runs free.
