only about 30 thrilling hours. don't get to ride it as much as i want, but it is a blast everytime i do ride it. i suprise ALOT of boaters when i go sailing by them. had alot of comments about it at the boat launch. our town is right on the st. lawrence river so sometimes on a calm night i'll pin it as i go by the park and sidewalks, alot of people looked suprised of how fast i'm going. hope to get some gps runs with it this summer to see what its actual speed is. hope to ride it more this summer.
