Brutal acceleration, extreme G forces and unpredictable sea conditions all add up to a waterborne motorsport experience like no other. These are lightweight, inflatable catamaran hulls with racing engines attached, developed originally from life-saving surf rescue craft and are amazingly stable and secure even at high speeds, round tight corners and in conditions ranging from complete calm to large breaking surf. Your experience will begin with a briefing on safety and handling before you head out onto the water with your instructor for 30 minutes of adrenaline-charged action (split into three ten minute stints). You will be shown exactly what this fantastic zapcat can do - so prepare for the ride of your life as you speed along, pull tight manoeuvres and hit big air jumps. Depending on the weather and at the instructor's discretion, you may even get the chance to take the helm yourself to try your hand at powering the zapcat across open water.
