May I ask how you get power to those 12 VDC plugs?
I have a +ve and -ve 12v buzz bars on both sides of the boat, switched from the main panel. All 12v appliances take their power from there. These are cool plugs as well, they actually clip into the socket very positively.
My concern would more likely be heat buildup where the notebook itself lives, the monitor and radios should be fine
Remember that the monitor on the notebook is turned off and the hard drive is hardly accessed at all when only a charting system is operational so the system isn't working that hard. But it is a point because the chart table isn't vented at all.
Do you have anything under the keyboard to keep it from slipping around while underway?
No, the little rubber studs under keep it reasonably skid-proof but then again, niether the mouse or the keyboard need to be left on the table when underway. MaxSea is set to auto-scroll with the current position always in the centre of the screen. So I guess the "accessories" will live on the shelf while we're sailing.
And the lamp . . . yeah the lamp. How did I walk into that??
It can't be shone, corroded, cheap-**** lamp, will have to replace it.
