I hear that. I picked up an old windsurf board off Craigslist for $75. Put a Gator Grip pad on it & have been using it as a paddleboard. The sail, mast & boom are in great shape so I'll probably get out there & learn how to windsurf (again.... it's been about 20 yrs).
I really got it for when I don't have anyone else around to go out & ride. But the ability to use it when it's windy is just another reason to have it.
