While mortals may never learn to walk on water, modern man can take comfort in his ability to sleep, text, or play backgammon atop the ocean. Enjoy some leisure on the water with today's Groupon: for $45, you get a half-day float rental from SeaDuction Floats (a $100 value). This deal is valid for locations in Bal Harbour and Sunny Isles Beach.

An innovative, water-ready vessel designed to handle two bathing-suit-clad loungers, the SeaDuction Float offers a shady chance to nap on the ocean's waterbed. Riders bob through the water while supported by a Super Schmooze cushion, which relaxers can use as a flotation device in the event their float is rammed by a Byzantine dromon. A retractable canopy covers skin from the sun for mid-afternoon siestas, and can be turned down for untrammeled views of the horizon. Umbrellas with vents open and close for additional sun-screening as passengers recline against wooden backrests and sip sudsy refreshments from the built-in ice cooler and storage containers. SeaDuction Floats come equipped with a buoy and anchor for resting in shallow waters, and can also be carried up on the beach to give newly minted sea legs a chance to bake on the dry land.
