As i said earlier in europe the fsrv boats were banned from running against surface driven boats because they kept winning

.Usually they run on M shaped courses so need to turn sharp and both ways,when i say sharp i mean in its own length round 1 buoy at full speed and to the next .I doubt a surface driven boat can do that as well they would just spin out.Top Speed is not allways the winner,turning quick and acceleration would win the day in my opinion.
