This boat to my knoledge isnot only the first boat in simple planes to reach the spead of sound but go 10 mph above it. Yes this is the same sub sonic boat but with more fuel, and with more weight it turns better in the water at high speed. It is very decevingly nimble for its speed and narrow shape, but this boat is desgined to roll agienst the centrafugal force of motion pulling on the top, (this causes most boats to roll over or capsize) with to tabalizers set to invert yaw (for ease of control) and two set verticaly. It uses 4 vtol engines and one afterburning engine. It is built with a sleek aerodinamic shape that hydroplanes on the water well. Its wake in reality would be miles long but in this game is as long as yeager airports airstrip at its current mesured top speed. This accedentaly was in my opinion the best boat ever builtr in this game that isnt a model, its garenteed the fastest unmoded boat. I've added airbrakes and a parachute to slow down .
