Here's my setup in my SRC 16' Quetico.
There's a hardwood board strapped to the yoke with two Clutch Straps (brand name, and very handy straps).
There are three Scotty Mount bases attached to the board.
From left to right inserted in the mounts are; Scotty Transducer Mount, then two Scotty rod holders.
Underneath is a Garmin Striker 4 Ice Fishing Bundle, this is a convenient bag with the fish finder, battery, and transducer all inside. I use it for ice fishing also and it can easily be moved to other boats. The transducer came with a suction mount, really for transoms, I found it came off the side of the canoe too often, so I added the Scotty Transducer Mount.
The Clutch Strap allow me to remove the whole thing in seconds, but keep it firmly in place when fishing.
Oh, in Ontario I can only fish with one rod. So only one is in the water at a time. I usually have one rigged for trolling, and the other for jigging.
