Re: rooster tail
a friend of mine used to take something similar to a "beer bong" out on the water. it was about a 4 foot length of 3/4-1" diameter tubing, with a 4-6" diameter funnel on the end. he attached the funnel to a piece of wood and he would dip the wood/funnel into the water while cruising and aim the hose at the person he wanted to soak. it worked pretty good as long as you could hold it steady in the water and didnt have too much extra tubing.
