Edson engineers designed this steerer with the working gear on the forward side of the rudderpost. This feature allows you to install this steering system on a yacht having as little as 5 - 6 in (12.7 cm - 15.2 cm) of space aft of the rudderpost (see "C" dimension in chart), depending on the size of the worm gear.
