If you allready have CT-360 pole and Tri-Stand. This would be the assembly you would select to transition the CT-360 pole to the boat. This assembly is also designed to be used with the Humminbird 360.  This is not compatible with the Humminbird Ice Fishing Pole.

The Base can be mounted directly to the boat, to the CT360 Scottie/Ram Holder mount, the CT360 Riser, the CT360 Pontoon mount or a plate for integrated sport tracks.  The Aluminum Cross Shaft is 14". The Humminbird 360 shaft slides into the 14" shaft assembly, which can be tightened. It comes with a depth collar so you can always set the transducer to the desired depth. When traveling you can rotate the assembly 90 degrees so the transducer is out of the water and secure.  This will come with instructions and Cobra Clips to secure your transducer cable.
