Does A68 require a CP100 so downvison sonar will work?

Thanks Chuck. So my hull will have a bump. It seems as though this will mean that the cpt will not be perpendicular to the hull (in order to get the transducer parallel to water)

Since I am a multihull, and there is virtually no heel, can a transom transducer be attached to a pole between my hulls to the waterline? Im thinking its something that can be retracted in seas but my main rationale for the sonar to begin with is in skinny water.
