FWIW:
I had been talking to the local Hobie dealer about buying a Wave. He told me that, although Hobie markets it as "car topable", every person he has sold one to has purchased the trailer. A couple of folks who purchased from him and didn't get the trailer, came back within a week stating that it was just way too much work.
They bought the trailer.
After hearing these stories, I decided to forego the Wave and buy a used H16.
Just FYI.
Fair Winds,
