Electric cars are now mainstream but electric boats have been lagging behind... until now.

The engineers at the New Zealand firm ZeroJet have spent the last eight years perfecting their electric jet motor and this is the result: a high performance, jet propulsion system which runs entirely on batteries.

Plus, they've partnered with the New Zealand company Offshore Cruising Tenders to offer a carbon fibre tender with a ZeroJet motor. The result is a highly maneuverable tender that's clean, quiet, cheap to run and loads of fun.

But how fast can it go? How far can it go? And how much does it cost? Click on the video to find out all of the above. And if you enjoy it, consider pressing the subscribe button for weekly content on electric powered cars, buses, boats and - coming soon - passenger planes!
