I can get some pictures this weekend, but I use one of the RAM mounts for my Garmin 276C, not unlike the picture above but smaller.

Its fine for cruising or motoring around, but always in the way when racing - constant complaints from crew (when they are not kicking it off the mount completely).

I'm convinced that if I could figure out a way to mount stuff under the companionway sliding hatch, this would work very well. Sliding the hatch forward would put things totally out of the way.

Just don't know how to deal with the cabling.
