keel on a sailing yacht).
• Be as near as possible to the center line of the vessel.
• Be clear of other through-hull fittings or projections.
• Have sufficient clearance inside the hull to fit the nut.
• Have 100 mm (4 in) of headroom to allow for withdrawal.
Note: In addition to the above requirements, the depth transducer
must be mounted within 10º of the vertical.
