Pivoting Instrument Rack

Before leaving for the San Juan Islands, I decided that I wanted to have a fixed mount VHF with masthead antenna and a depth sounder as well as GPS mounted where I could see them underway. The LED displays can be hard to read unless the light is just right. Although it would be desirable to have a rugged mounting for the instruments, I didn't see a way to do that for now. The next best solution was to mount all three instruments on a swing out rack so they would be in the middle of the hatch where they would be easy to read from a sitting position on port or starboard but would easily swing out of the way. Here's my solution.

 

The shelf swings back on top of the binocular rack on the port side of the boat. The little wedge at the end locks it is position. In the same picture, you can see the two power outlets and running and compass light switches. I wanted to be able to control the running lights without having to go below. The sliding hatch can be closed over the instruments. Surprisingly, the GPS continues to track with the hatch closed.

The fishfinder transducer mounting is shown in the last picture. The board clips onto the hull, right ahead of the rudder. The triangular wedge is designed to keep weeds from accumulating on the transducer. I lead the wire from the transducer through the drain hole in the transom and up to the fishfinder along the cockpit sole. The power for all three insturments on the rack comes from one of the outlets on the panel. The whole rack can be lifted off once the power is unplugged and the antenna and depthsounder wires are removed. I can pick the GPS out of the holder and it will continue operation on the internal batteries.

It isn't pretty but it works.
