While it's not quite as high on the insanity meter as a jet-powered shopping cart
, or port-a-potty
, we still wouldn't want to go anywhere near Shaun Baker's self-made jet kayak, which he apparently decided to build after deeming the sport not dangerous enough. Costing about $10,000, the kayak packs a 45-horsepower engine and is steered simply using a regular kayak paddle. As you can see in the video after the break (from an episode of Top Gear), the kayak is also far from simply being a proof of concept, with it already having been pushed to the limit in a race -- against a Land Rover Tomcat 4x4, naturally.
