Cranes Mill Marina gives landlubbers the chance to become aquatic adventurers on its fleet of rentable watercrafts. A three-hour eight passenger ski-boat rental lets speed demons tug along delighted adrenaline junkies on the included wake board, kneeboard, tube, or water skis. Slower-moving seafarers can climb aboard a 24-foot-long, party-ready pontoon boat, which has a flat bottom easily used as a dance floor or roller-skating rink. The pontoon boat ferries up to 11 cadets at an ambling, luxurious pace, making it a sturdy hub for swimming excursions, easy-going fishing trips, or an afternoon spent gazing at the lake's natural beauty.

For a more intimate lakegoing experience, marry a catfish, or opt for a jet ski, a speedy, streamlined skimming machine on which one or two people can cruise across the water. The maritime merrymaking is facilitated by the included life jackets, water toys, and fuel.
