The Ocean Scooter. Designed to annoy everyone in the swimming pool and get you lost at sea with no possibility of getting back to land, this 12v/7Ah "battery powered inflatable watercraft" can travel at a swooshtastic 2.5 miles per hour and carry up to 165 pounds. It features an "aerodynamic design", dual air chambers made of PVC and, lo and behold, an on/off switch. The demonstration video after the jump can only be watched at 3am after a bottle of tequila and five bags of Flamin' Hot Crunchy Cheetos.
At $395, I will stick to paddling on my inflatable rubber chicken.
