Those guys have a variety of toys and not all are inflatable. I used to get a glimpse of them heading out from Rudee Inlet in 25'-30' cigarette style boats. Twin mercurser I/O that sounded like the props where being turned by big block V8s. They'd go out in groups of 4 with about a 1 minutes gap between them. I never did know how fast they went, but from the time they cleared the inlet to the time you couldn't see them anymore seemed like only a minute or two. They get all the cool toys.......
