Installing the thru-hull mount transducer

Transducer mounting location

This type of mounting provides the best performance of all, since the transducer protrudes from the hull and the effect of air bubbles and turbulence neat the hull skin is reduced. When the boat has a keel, the transducer should be at least 30 cm away from it. Typical through hull mountings are shown in the figure on the next page.

The performance of the video sounder is directly related to the mounting location of the transducer, especially for high-speed cruis- ing. The installation should be planned in advance, keeping the standard cable length (8 m) and the following factors in mind:

•Air bubbles and turbulence caused by movement of the boat seriously degrade the sounding capability of the transducer. The transducer should, therefore, be located in a position where wa- ter flow is the smoothest. Noise from the propellers also ad- versely affects performance and the transducer should not be mounted nearby. The lifting strakes are notorious for creating acoustic noise, and these must be avoided by keeping the trans- ducer inboard of them.

•The transducer must always remain submerged, even when the boat is rolling, pitching or up on a plane at high speed.

•A practical choice would be somewhere between 1/3 and 1/2 of the boat's length from the stern. For planing hulls, a practical location is generally rather far astern, so that the transducer is always in water regardless of the planing attitude.
