First Sailing Terms Tutorial should use Yacht
The first tutorial on sailing terms is part of the yacht tutorial, but it uses a dinghy. So that's confusing. And then you have to do the same thing again when you do the dinghy tutorial (boring).
We need both... Users can select if they want to start with Dinghy or Yacht. And in fact, Dinghy will be the one we will encourage to start with ( simpler, just 1 sail )
