"each of the crew output 1.5kW?"
If that's the peak output they can manage for a few seconds, it's not entirely unreasonable. That's the sort of level top cyclists can manage for sprints lasting no more than a few seconds. 3-400 W is the most that could be expected on any kind of sustained basis.
As for the app:
"the app’s display shows not only the boat’s position overlaid on the racecourse but also turning points, distance to go to next waypoint, boat speed and it even automatically changes view to zoom in at critical moments – all without any interaction from Scott"
So it's an entirely standard GPS navigation app. My watch does the same, as does Google maps. It seems odd for the article to spend so much time going on about it when it's probably the least interesting part of the whole thing.
