When the Bladeriders first hit the states, I sold my A-cat and bought one. I was fortunate to have the current world champion as my personal coach for a week at the US Sailing center in Miami.

At the end of the first day I would have sold you the Moth for $1.
After 2 days, I was able to ride it more than 30 secs without crashing.
After 5 days, I could get it up on foils and keep it there for an extended amount of time.

I brought it back to Lanier and attempted to lake sail it.

Within 6 months I had sold it to buy another A-cat.

I found that it was fantastic to sail it where there was a sea breeze. Sailing it on a lake, not so much...
