Dave,

We did that a few weeks ago with the Nacra 5.2 I bought. I had the sail up and was wheeling it to my driveway with a second set of cat wheels and the wind from the east. We hopped on and rode it from the club building up to my Dad's trailer. We were picking up speed quickly and decided to slow it down before we hit the closed gate at the front of the club. Even with two of us on the boat and the wind less than 15 kts, its amazing how fast a sailboat will go on land with wheels.
