Until water was invented, the sole purpose of owning a boat was to light it on fire and use the open flames to cook skewers of sushi. Discover the most practical use for a boat with today’s Groupon: for $40, you get a dinner cruise from Spirit of Norfolk (up to a $78.34 value including taxes and fees, varying based on departure time). This Groupon is only good for the dinner and early dinner cruises, and only for the early dinner cruise on Saturdays.

Spirit of Norfolk offers an entertaining evening of dining, dancing, and taking in the scenic views of the Elizabeth River waterfront and Norfolk harbor. On board a luxurious Coast Guard–certified yacht that can carry up to 450 passengers, guests enjoy a three-hour cruise that comes with a dinner buffet. Cozy up to a candlelit cabaret table to fill your food compartment with fresh salads, beef and ham slices from carving stations, tasty entrees, and sweet desserts, while washing it all down with mixed drinks, beer, and wine, which can be purchased at the bar.

After leaving its comfortable berth, the Spirit cruises past points of interest such as Old Fort Norfolk, which housed Confederate prisoners of war during the Civil War, Norfolk Naval Base, and the site of the 1862 Monitor/Merrimac battle, which marked the first time two ironclad warships pelted each other with overly ripe fruit. While taking in the sights, DJs spin hot beats and the multitalented Spirit of Norfolk wait staff sing songs, filling the double dance floors with danceable melody.

The Spirit of Norfolk’s dinner cruise departs from the Waterside Festival Marketplace in downtown Norfolk at various times every day of the week (boarding times vary from 5:30 p.m. to 7:30 p.m.). An early dinner option is also available. Proper attire is required to ride the ship.
