Just out of curiosity, what’s your design intention here?
Yacht is directly replicating an existing ability, with no additions or modifications of any kind to differentiate it. Keywording abilities to save space or allow for more complicated effects is perfectly fine, but this one is relatively short and simple already.
More significantly, on the only ship where it appears in your list, it’s paired up with a mutually-exclusive ability. There’s no possible (legal) way that ship could use both abilities at the same time. That’s very much something Wizkids might do to fill out a set, but I guess I don’t see the value in creating ships for custom sets that are intentionally wasting points (or worse, are purposely meant to be bad).
