Though tattered ragamuffins with gambling hands are prone to dining with the fishes, it's the esteemed members of land-society who dine atop the fishes. Merge seafaring and supping proclivities with today's Groupon for a cruise of Boston Harbor aboard the Odyssey. Choose between the following options:

• For $50, you get a three-hour twilight dinner cruise on Sunday (a $94.19 value). Boarding times vary, but Sunday cruises generally start boarding at 5 p.m. at Rowes Wharf.
• For $60, you get a three-hour dinner cruise on Friday (a $117.77 value). Boarding times vary, but Friday cruises generally start boarding at 6 p.m. at Rowes Wharf.
For $70, you get a three-hour dinner cruise on Saturday (a $143.97 value). Boarding times vary, but Saturday cruises generally start boarding at 7 p.m. at Rowes Wharf.

The Odyssey treats up to 600 revelers to fine dining, music, and dancing with the Boston Harbor lights as a backdrop. Step aboard and tour the ship as she casts off from Rowes Wharf. Shortly after being put to sea on the three-hour Friday or Saturday dinner cruise, cruisers can enjoy a three-course meal chosen from a menu of first courses, entrées, and desserts. Before sweet teeth reap the rewards of dessert, sink them into a nutritious entrée brimming with fresh ingredients such as the argentinian salmon bedecked in spicy chimichurri sauce and crispy corn-tortilla strips, caramelized duck en croute, or peach-glazed pork tenderloin. The Sunday Twilight Dinner cruise, running June through August, treats end-of-weekend warriors to a special plated menu complemented by a generous helping of beautiful views.

Once sea legs grow, take them for a spin on the dance floor, where the ship's live band plays the hottest hornpipes and sea chanteys, or climb to the ship's top deck, a spacious floating patio that offers breathtaking views of the city.

The Odyssey sometimes features a discount online, but this Groupon still offers the best deal available.
