This sounds like a classical telemetry application where a machine (in this case the boat) was instrumented with real-time sensors to collect information, which was then used to tune the machine. There is nothing new about this. Airplanes, cars, vending machines, industrial automation all do this. IoT implies that these devices and their data create value when shared on a larger scale to a bigger audience than just the local (controller). I don't see a case here for sharing the data to a wider audience? What is the value prop for doing so? Why does anyone outside care? IoT means more than just a network of sensors and actuators - doesn't it? A company in Singapore, DatastreamX, is trying to connect data from diverse sensors to those who have a need - on a grand scale. I think this particular example here is not hitting the mark for IoT.
