Mako Slingshot Jetboard

The Mako Slingshot jetboard is a carbon-fiber, gasoline-powered surfboard built around a Rotron aerospace-grade jet propulsion system, engineered to fly across the water at up to 55 km/h.

The Design

Mako drew directly from marine biology to shape the Slingshot: a torpedo-profile, muscular carbon-fiber jetboard whose lines mimic the streamlined body of a predator built to glide through its own habitat. The wave-piercing nose, thick rear volumes and precisely placed foot planes read like a shark redesigned in a state-of-the-art composites factory. A single monocoque hull keeps weight to a minimum and gives the Slingshot the light, reactive feel of a shortboard rather than a heavy motorized craft.

On the Water

Under the deck sits the Rotron XT1100 propulsion unit, a direct-drive axial-flow water-jet pump paired with a high-revving 993 mm three-blade impeller machined from aerospace materials. Water is forced through a twisted stator that keeps thrust in line and makes steering intuitive, while the compact 100cc, race-tuned two-stroke engine (British-built by Rotron Power) puts out 12 hp at 7,800 rpm and 10 lb-ft at 6,400 rpm. The result is instant traction as soon as you squeeze the throttle, and a confident push through chop or flat water alike.
