Other transducer types are also available for specific requirements. For further

flow areas indicated by the shaded areas in the following diagram.
The transducer should also:
• Be ahead of the propellers (by a minimum of 10% of the water line length).
• Be at least 6 in (150 mm) away from the keel (ideally ahead of the keel if a sail-
ing yacht).
• Be as near as possible to the center line of the vessel.
