Known as the ElectraFin, it consists of a polyethylene housing that encompasses the 240-volt motor, propellor, and fin, a 14.6-volt lithium-ion battery pack in a waterproof housing, and a wrist-worn speed controller.
The motor can reportedly be installed under the fin box a typical SUP in under a minute, and it’s connected to the topside-mounted battery pack by a cord. The whole apparatus weighs 14 pounds, and can propel a board at 5 mph for about 4 miles or about 16 miles.
The battery pack requires a one-hour recharged for every two hours of use. The wireless wrist-remote runs for over 100 hours per charge, and will shut off the motor if it’s more than 10 feet away, keeping the board from going out of control if the rider falls off.
Current Drives is currently (pun intended) running an Indiegogo campaign to raise money for the ElectraFin. An $850 pledge nets the complete system, while $1,600 gets an inflatable SUP designed specifically for ElectraFin. There’s also a version planned for kayaks.
