From Engadget:

Nah, the WaveBreaker probably won't provide the kind of thrills that a jet-powered kayak would, but riding around on this thing is a lot less likely to leave you maimed. This electric, inflatable watercraft comes loaded with a 600-watt motor, weighs 66-pounds, and touts the ability to scoot around for "45 to 75 minutes" before needing a recharge.
