Crank this Lake and Sea Pedal Boat up to its top speed of 4mph and people will yell at you from the lakeshore that you’re in a “slow no wake” area. It’ll take awhile for the tow rope to straighten out, and you’ll have to pedal really hard when turning corners and pulling water skiers, but at least you won’t be pumping gas into the lake. It only costs about $4000—the same price as a used ski boat or new canoe.
