Side Scan Sonar

[Kiwidiver]

Transducer mounting location?
I have a leopard 39 cat (37ft). As an avid diver i am looking at installing a garmin echomap 95sv with a side scan transducer for wreck and dive site mapping. The Garmin and side scan is separate from the main boat navigational equipment. I have raymarine depth, chart plotter and auto pilot for sailing. The question I have is where to mount the transducer?

Forward of the keel i dont have good access on the inside of the hull. Beside the keel I have access but would loose one side of the scan as the keel would be in the way which would mean having two transducers with one on each keel (expensive + an extra hole in a keel)

What looks like the best position would be directly (about a foot) behind the keel and before the sail drive. Has anybody done this or something similar? does anyone foresee problems with this location?

any input appreciated.

You really wan't the transducer as steady as possible. Thus I prefer having it on a tow fish as it eliminates most of the wave induced noice of sonar files. Yes, files becouse you wan't to look at the scans on a big computer screen to get clear look at the details.
Just for navigation for a narrow passage any other place is ok..

I would like to install a Lowrance sidescan, for the same purpose, on my sailboat. Have you had any success with your project?
I was thinking of mounting the transducer to a PVC pipe projecting down about 4' from the transom. (I would mount it where my self-steering rudder mounts)
Any thoughts on this would be greatly appreciated.

Is this only used at low speed for mapping? Maybe on a spar or tow from the bow cross bar.
