A sea voyage is like a trackless train ride across the water fields, relying only on the principles of physics and magic to keep your vessel floating above the water on a thin cushion of air. Unfurl your sea wings with today’s Groupon: for $199, you get 2.5 hours of shared sailing for two people on Pianissimo from Lakeshore Sail Charters (up to a $487.50 value).

Lakeshore Sail Charters guides seafarers on a serene, luxurious cruise around Lake Michigan, enticing passengers to relax on board one of the three ships in its fleet—including Pianissimo, a 2011 Beneteau Oceanis 50. On each voyage, aqua-adventurers are guided by the steady, calloused hands and windblown visages of U.S. Coast Guard–licensed Captain Bruce Randall and the ship’s doctor, Karen Randall. At the whim of the wind's desire, no two tours on Pianissimo are alike. In between basking in the picturesque skyline views, passengers can peruse Pianissimo's amenities, including a radio, a CD player for playing Arnold Schwarzenegger Making Ocean Sounds, and a microwave.

Sailing times are at 5 p.m. and 8 p.m. Mondays–Fridays and 8 a.m. and 11 a.m. Saturdays and Sundays. The Wednesday 8 p.m. sail requires an additional fee of $30 per person.
