More importantly than just momentary boat speed is the total time up on foils. Jimmy, Dean, and Ben have all said in recent interviews that foiling the entire race is possible. In recent practice races you could see examples of where one boat fell off foil and slammed down, slowing let's say from 40 mph to 20 mph, that the other boat picked up so many boat lengths that the race was basically over. That speed difference would give them 10 boat lengths in just 15 seconds of "down time".

Fast and steady wins the race.
