Every season I see a few more. And the Torqueedo is gaining, too. I haven't seen one sailing yet (except in video's).
You can debate the pro's and con's of dinghys, but one thing remains, the Pudgy is on the small size for a tender. At 8', they're bigger than most 8'ers in carrying and safety. But performance under oar, sail and power drops drastically with extra weight(not a Pudgy problem, and 8' problem).
Still they are a great idea for many boaters.
