SPORTJET 460 The Sportjet 460 has added space and a bit more growl, with a lightning-fast top speed of 48mph (77kph). The specially designed hull plants it firmly in the water for safe, straight-line tracking, yet it grips hard in the turns. When you want it for more sensible duties, it per forms as a smooth, stable people carrier for getting to and from the jetty, and will fit on the back of 25m+/82ft+ motor yachts. It’s equally at home as a standalone day boat for coastal exploring, as it is as a white-knuckle ski boat.
