The body, which seats one-to-three people, is Shadow Six's own design, although according to GearJunkie it wears aftermarket body panels from a Polaris RZR side-by-side. The twin jet ski hulls are in-house builds too, in carbon composite, and they're mounted to long-travel Fox shocks front and rear, that look like they'd be right at home on a UTV.

Inside these two hulls sit two 1.8-liter supercharged Yamaha GP1800R SVHO jet-ski engines, putting out 250 horsepower (186.5 kW) apiece. Should you deem these ponies insufficient, you can choose stage 1, 2 or 3 Riva Racing performance kits to be installed before delivery. Riva won't put exact numbers on the power boost involved, but says a pair of Stage 3 kits will take the Typhoon's standard 68 mph (109 km/h) top speed up to "well over" 80 mph (129 km/h).
