On the Intracoastal Waterway near Dania Beach, Ivan Bertaska is getting ready to captain his vessel.
Bertaska wants to check the boat’s capabilities by having it speed up and slow down as it carves a wavy wake across the Intracoastal.
“The wave pattern actually gives me a good range of velocities," he says, "so at first we go about two knots and then we get to the top corners where we’re making sharp turns and we’re going about one knot. So I get a good operational range of the vehicle.
"We get a lot of funny looks from boaters.”
