I recall the Hobie sales sheet showing the boat quite low in the water with a single adult aboard. Without the raised trampoline on the 14/16 it looked like it could be a bit of a wet ride.
I don't know where you're based but the Catapult could be a better option for a 1 or 2 person car-topable cat. Also consider the Sprint 15 (Dart 15/Spark).
