Speed boat racing is one of the most dangerous forms of water sports there is.
These guys travel at 70mph on water and a small wave only 3 feet high can abruptly change the trajectory of the vessel sending is in the air or under water.
This is what happened with this boat crew during a race. After a slow start the former champion was making ground and pushing the speed boat to the limit, and apparently over it. After hitting a rogue wave the boat launches into the air and then violently slams under the see turning it in one of the fastest submarines for a split second.
Watch one of the fastest and scariest decelerations from 70mph to a standstill that we have ever seen, the g-forces must have been brutal on that one.
