The vertical rib on the drum firmly grip the line, requiring fewer turns to achieve the same holding grip as conventional winches. The self-tailing mechanism automatically accommodates a wide range of sheet and halyard sizes, making these winches useful in trimming sheets, hoisting halyards, and making other adjustments.
