(port "P", starboard (S) or all–in–one "0°" ) for your chosen mounting location.
2. Align the bottom half of the fairing block on the hull so that it is parallel to the centerline (keel) of
the vessel, ensuring that the pointed end of the fairing is pointed towards the bow.
3. Using a permanent marker, draw around the outside edge of the fairing block and the internal
holes for the transducer stem and anti-rotation bolt.
