Bodies of water are frequent metaphors in poetry due to their unfathomable depths, unknowable sprawl, and unattainable porpoises. Set sail into the enigma with today's Groupon: for $149, you get a five-hour pontoon-boat rental from Bass Lake Water Sports (a $299 value).

Bass Lake Water Sports' patio-style pontoon boats seat up to 14 passengers along frothy spumes during picturesque expeditions throughout mornings and afternoons. The easy-to-drive vessels come equipped with life vests for all shipmates, an AM/FM radio, and a towing hook that's great for pulling inner tubes or freeloading belugas. Fishermen can reel in their next meals from the deck before barbecuing legendary catches with the boat's supply of propane. A canvas top covers nearly half of the pontoon, providing shade from the sun's body-weakening rays and overhead protection from dive-bombing weather balloons. Although not included in today's Groupon, boat renters can stop at the marina store to stock up on fishing and other boat supplies.
