Here's a pic of our's
2 580lb sacks in starboard side rear storage.
Front, center and starboard factory ballast full.
3 passengers and 1 driver on starboard seats.
9-9.5 mph on cruise control.
We've tested the port side with similar set up, seems to be about the same. You'll need to decide which side you ride based upon which foot forward you ride, and whether or not you'll ride heel or toe side. Lastly, of course we recommend XBC boards!
