About these drag races. Are they common? If so, that is pretty cool.
Depends on the boat and Skipper...sometimes they can be disguised as leap frogs or hi speed run testing. All I know is that with a 10,000 ton vessel and 105,000 shaft horsepower the rooster tail get's about 20 - 30 feet tall aft of the fantail.
