Alignment
The arm can rotate freely around the base. When the rudder is amidships, the arrow on the arm must
point to one of the centre lines on the base.
Therefore in an installation, the base can be rotated to two positions. We recommend the position that
has the cable on the opposite side to the connecting rod.
Arrangements
Recommended: U-shaped arrangement with the arm parallel to the length of boat:
