OK Gundog, here goes...
In the upper right on a RAM mount is the GPS/Fishfinder combo. The display lower and to the left is my radar on a Johnny Ray mount. My VHF is on the passenger side under the glove box. The fuel flow meter is the round guage on the far right under the GPS. The trim tab switches are going to go under the fuel flow as soon as I can afford the trim tabs to attach'em to. :tongue:
On my last boat I had the Fish finder low on the left where my radar is in this picture. My fishing friends always wanted to watch the screen, so I always had it tilted to the left and it was harder for me to see.
In addition, since the throttle is on the right you'll typically steer with your left. That meant you would want to control the buttons with your steering hand
or cross over with your right. I did the crossover mostly since I'm right handed. That was an awkward wat to adjust the FF pointing away from that side.
With the GPS/FF on the right and high it's good for everyone's viewing and the controls are MUCH easier to get to by letting go of the throttle rather than the wheel. The RAM mount is very versatile in that corner location.
The only place left for the radar is where it is now, and a RAM mount would not work with the space there, hence, the Johnny Ray mount.
The spacings required from radio unit to anntenae and between antennaes made me put the VHF where it is. I also wanted to eliminate any interference between the sonar/transducer and the radio. That can make for very annoying radio reception.
The fuel flow is right over wher the controls are for the fuel and the tab controls will be right there also. Throttle, trim and tabs all affect fuel consumption so I thought that having them all right there together with the meter would be efficient.
I'm still trying to figure out where to put a compass so that it has even the slightest chance of pointing north
This will be similar to the space you'll be working with, hope it helps.
I'm more than happy to answer any other questions.
