[C38] Radar installation advice

[Charles]

I am installing radar on the Mighty Quinn in preparation for my trip 
through the Great Lakes this summer which will include wandering among 
giant steel battering rams (commercial shipping), who don't wish to 
debate navigation rules.  Tonnage rules is the byword and my personal 
experience crewing on a 600' ore boat back in the 1960's supports this 
as part of my night watch responsibilities was to make sure the pilot 
was awake.... and yes I often had to wake him!
I have purchased the Furuno 1715 during the Defender spring sale.  It 
comes with 30 meters of cable to connect the masthead unit to the panel. 
1. Is this enough and
2. where did folks mount the control unit and run the cable?
