Back in the day when a 35 HP outboard was the biggest one made, many of us youngins had rooster tails just to look cool. It also made the girls think our boats were faster than they really were.
It wasn't because it was a jet, or because the motor was trimmed too high, it was merely a gadget that cost only a couple bucks and it was mounted on the transom. The really cheep guys used a soup can because they didn't want to spend the $2.00.
I don't know if they make them any more, but I'm sure if you google the concept you'll learn all you want to know.
Or, look at the back of a Yamaha jetski (waverunner) They call their rooster tail a "visibility spout". It mounts behind the jet pump and directs water thru a port on the swim deck. With a little ingenuity I'm sure a guy could farbicate such a bracket and screw it to the bottom of his transom.
(PS - Cigar boat? Or, do you mean cigarette?)
