Bodies of water are frequent metaphors used in poetry, due to their unfathomable depths, unknowable sprawl, and unattainable porpoises. Set sail into the enigma with today's Groupon: an hour-and-a-half sunset cruise for up to five people on Lake Erie from Fast1Charters. Cruises depart from the Edgewater Ramps on Wednesdays, Thursdays, and Fridays at 7 p.m. Reservations must be made at least 48 hours in advance. This Groupon expires on 9/17, so head out before the water migrates south for the winter. Choose from four options:

• $60 for two tickets (a $100 value)
• $90 for three tickets (a $150 value)
• $120 for four tickets (a $200 value)
• $150 for five tickets (a $250 value)

Round up your closest friends or take your sweetie out for a romantic ride aboard Fast1Charter's high-speed racing boat for an exhilarating and breathtaking outdoor experience. Captain Greg will ably pilot a 35-foot cigarette powerboat over Lake Erie's tranquil waters and lake dragons. During your cruise west from Edgewater to Rocky River, you'll enjoy the rush of 70-mile-per-hour speeds while the sun bobs atop the water like a perfectly safe yet radioactive buoy. On the way back, you'll get dramatic views of Cleveland's lit-up skyline pitched against the water. As you watch the sun melt into the ripply waters, pair your eye feast with an occasional cooling freshwater spritz.

Fast1Charters' sunset cruise is BYOB, so bring along a couple of beers and toast your pals as you snuggle into the wind's exhilarating embrace.

All cruises are weather permitting. Expires 9/17.
