You won't see a One Design pass BJM and his Activator in rough conditions, but its not uncommon for us to pass some of the slower F-1 's in 4 - 6 footers.
Take a look at the average lap times of the winning F-1 boat and One Design boat in both Clevland (smooth water) and Savannah (a little rough).
Winning F-1 avg. lap speed: 76.30 mph
Winning OD avg. lap speed: 64.12 mph
Winning F-1 avg. lap speed: 62.78 mph
Winning OD avg. lap speed: 60.18 mph
The rougher the conditions (within reason), the closer the lap times of the two classes. Super Vee Light Single is only a mph or so ahead of the F-1 speeds in both races (77.59 in Cleveland, and 63.24 in Savannah).
Keep in mind that the One Design is powered by a stock 315 hp Volvo, compared to the 500 hp in the F-1's.
Come to Bahamas or Key West and find out yourself. . . probably the only race boat/class that offers demo rides to the interested public!
