[Vasco]

I have a Raymarine system which is capable of doing all of what you listed. It's a nice toy, it's a useful toy but don't ever rely on it solely! My brand new boat got hit while at anchor in the Bahamas by a 46' Irwin piloted by a couple of idiots that couldn't take their eyes off the computer screen ! They came right at me for over five minutes and not one of the four adults aboard was keeping a lookout. This was in broad daylight . GPS and chartplotters have made cruising easier but it's also unleashed some real idiots. By the way, the owner/skipper of the boat that hit me had a six pack license and also claimed to be a charter skipper.
