There are quite a few arm type devices you can use, look for monitor stands as one possibility. One thing to be aware of, is many are made of mild steel and very susceptible to corrosion in a marine environment.
I would probably go for a 12 VDC computer with a flat panel that was mounted on a swing away arm, and leave the chart table top basically clear. If you use a wireless keyboard and mouse, then it becomes quite simple to keep everything out of your way.
