Machined aluminium drum stronger and lighter than traditional cast aluminium drums.

Lightweight aluminium centre stem provides significant weight savings over traditional bronze stems.

Low line entry due to gearing configuration geometry.

The innovative QuickTrim self tailer allows sailors to easily and safely ease line tension to make minor sail trim adjustments without having to remove the winch handle or take the line out of the self-tailer. Racing sailors can react and respond instantly to minor changes in wind direction or steering, providing an unmatched advantage when frequent sail trim adjustments are required. It’s also a nice convenience for cruising sailors.

On the water, using QuickTrim is intuitive and quickly becomes second nature. With one hand on the tail of the sheet, rotating the top cover of the winch anti-clockwise against spring pressure allows the self tailer to turn beneath it like a sheave as the rope is eased out, with smooth grip and control assured by the drum surface and Power Ribs. When the top cover is allowed to spring back, the self-tailer locks again and grips the line to resume normal use. This simple, reliable feature is a real advantage when making frequent minor adjustments to sheet and halyard tension.
