Power boaters

I am not referring to power boaters in general, just these, one-two-three-four-five-six seven-eight-nine-ten-eleven-twelve-thirteen-fourteen-fifteen-sixteen-seventeen-eighteen-ninteen-twenty power boaters in particular. They raced at full throttle past us in a row, going out of their way to annoy us. And whenever they are close together, they produce constructive interference, making double the wake size. Once our stern got dunked into the water, soaking the helm seat. What word do you have to describe them?
