Unveiled at this year’s Surf Expo, the WaveJet generates 20lbs of thrust, has a continuous run-time of over 30 minutes, and recharges in a standard wall socket. An innate flaw is a lot of surfers are environmentally conscious as well as exercise fanatics which means they're not lazy and don't enjoy draining resources either. They might change their minds, however, when they see how much fun you’re having – so long as you don’t look like a total prat when it comes to the surfing itself.

The jets are controlled via a wrist-strap remote and it's particularly suitable for unfit beginners. One of its main advantages is allowing you to surf for longer (on account of the energy it'll save you) which means you'll still be out at sea while everyone else is completing laborious tasks such as collecting firewood for the night's camping. Bonus.
