The Raymarine remote display app is basically remote desktop (or VNC) for the plotter and gives you a second interactive display anywhere that you want it on the boat. If I'm anchored in an unusual situation I'll leave my cockpit plotter turned on and use the remote display below to keep an eye on our depth and location.
