DESCRIPTION

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.
