Not sure if this has ever been discussed...
But this past summer I tried doing some "endurance WakeSurfing" In which i would attempt to surf at my regular speed (11.2 mph) and slowly bump it up to speeds i can consistently ride at for at least for 15 seconds (which is usually when i get pretty exhausted).
The fastest speed I've been able to ride for 15 seconds is 14.9 mph on my inland surfer 4 skim moss.
So my question is, What's the fastest you've WakeSurfed?
Plz list the board you used too (i know that makes a big difference. As well as boat, ballast, etc..)
