River cruises are a luxurious way to relax and see the sights, unlike boarding dolphins equipped with saddles, which usually results in whiplash and water-filled lungs. Cruise the blue in comfort with today's Groupon: for $49, you get a ticket to the Wine & Tapas Boat Cruise from Fort Washington Potomac River Tours (a $100 value). Cruises begin at the National Harbor in Maryland, and are available through Dec. 1, 2010 (must schedule by July 1, 2010).

Fort Washington Potomac River Tours takes to the waterways of the Washington, DC, area to provide passengers with an elegant and intimate experience aboard a luxury yacht. Board the custom-built, 64-foot Pelican and cruise the currents of the Potomac River in style—the ship is equipped with a large main salon, a full galley, an enclosed party deck, and satellite TV, allowing guests to tune in to live broadcasts from George Washington. During the Wine & Tapas Boat Cruise, passengers will enjoy two glasses of wine and a tantalizing tapas menu while treating ears to a 2.5-hour narrated exploration of the Potomac River, with a guide sharing historical anecdotes and pointing out notable landmarks along the way. Tours are available throughout the summer—check the schedule for dates and times.

As a bonus, Fort Washington Potomac River Tours is offering a special discount with this deal—Groupon purchasers will receive a $1,000 credit toward the purchase of a Fort Washington Potomac River Tours standard three-hour charter package (pricing depends on customization of services provided, including meal and beverage requests). A $500 deposit to secure charter time and date is required for that additional trip. Corporate rates are also available for those interested in seeing how junior executives hold up under the pressure of breathtaking views and luxurious yachting.

Although you may use your Groupon on any Wine & Tapas cruise until Dec. 1, 2010, you must schedule your cruise by July 1, 2010.

Guests must be at least 21 years of age.
