what was the cost of the screen?
That's Awesome - thanks for Sharing!
with regard to Power, I found that I didn't trust other boat users to not turn the power off at the switches accidently so I added some simple electronics to my Pi to make the schematic below:
[
attachment=1349]
with this the switched power is connected to the breaker panel and the const 12V is connected to battery, if the switched voltage goes off it is sensed at pin 40 and a power down is started, once the Pi shuts down, the relay is turned off, disconnecting the constant 12V. the hardware costs less than $10 and looks like the below:

By connecting a momentary switch between pin 40 and ground, you can also start the shutdown process when pressed

194 USD plus freight (51 USD to Spain). I paid via PAYPAL

A foolproof solution!
Thanks for the idea
[
attachment=1356][
attachment=1357]A complementtary data screen for regatta tactics, can be obtained free for the NKE web. (née display) for your smartphone
Connect smartphone with "open plotter" wifi network from your OP RPi
Set to 10.10.10.1. and port 10110
and all your navigation data will be on the NKE display (8 different screens of data)
Of course, with the web explorer in the phone (or tablet) can also access to KIP pages in the same way as in the waterproof display.
Simply connect with
http://10.10.10.1:3000/@mxtommy/kip/#/1 (1 or the nº of the page you want to show first)
Put this URL in favorite markers as KIP
That's easy, fast, and ZERO cost
Do you think it is waterproof enough? With all boards exposed (even though they are inside of enclosure).
Might be better to put smaller boards into potting epoxy, cover pigtails connections with heat shrink tubing.
Larger boards into waterproof enclosures with cable glands for wires coming out?
There possible condensate water in such cockpit enclosures.
Thanks

This arrangement has been operating in the boat cockpit during eight months and is completely water tight. No water condensation is seen when inspected the inside of the box
Of course, there is no water vapor barrier, thus; can be potentially affected by the excess of humidity at long term. (But no very different of conditions for the RPI running OP in the boat's cabin during winter)
As the relay board will be eliminated, and the supply adapter is totally enclosed, I will study a small resin box tho accommodate the RPI inside with connections through tight seals. (good projects never are really finished!)
The display looks to be good enough for outdoor work (Sihovision sell those displays for marine equipment) and bezel material seems good enough for salted water sprays. (But, must wait two or three years to be sure...)
Thanks for your suggestion

Daylight viewing is OK ?
Good enough, even at 45% from vertical and under high sun. (better if installed vertically)
But it has a certain "mirror" effect. I placed this question to Shiovision, and I was told that the capacitive touchscreen is better in this aspect. (mine is restive touchscreen)
