and hive_angel, it's really silly to roll, for piloting rolls, when your jumping over water. You are not entering water, you're entering hex with water, why would jumping over deep water be more difficult than jumping over depth 1 water, and they incur different piloting roll penalties.
please do agree that even if your interpreation is legal we'll house rule it so that if you walk or run through the water you make piloting rolls, but if you jump over it you only roll for the one you land on.
