I will just add that if marine electronics goes the way of aviation electronics, we should see a lot of stuff migrating to the Ipad and leaving the specialized boxes of electronics and displays we have been buyiing, cabling and replacing, behind. Those of you who are pilots know that, in just a few years, most GA pilots are largely ignoring all the very expensive and complicated avionics in the GA aircraft and using the substantially better technology and software of the Ipad for operation, navigation and collision avoidance--the brain of an Ipad is way more capable than the chips they generally put in the boxes. Furuno did it with the radar but the other marine electronic folks are still trying to get us to buy a lot of old, weak technology in boxes that we have to jump through hoops to network with very expensive and proprietary network cables. I think all this stuff is going the way of Almond colored kitchen appliances in the near future. You really should be able to plan a trip and integrate the weather (and weather updates and warnings) and have the device steer the boat in real time, alert you to traffic and hazards and monitor the technical and engine performance of your craft. The Ipad can do that for aviation right now and it should be able to do that shortly for boats if we stop buying boxes and proprietary cables. But I just bought a bunch of marine boxes and cables--we are not there yet. FWIW.
