Since the dawn of humanity, man has longed to conquer the ocean, which is why the invention of the boat was followed swiftly by the adoption of the high-five. Celebrate man’s triumphs with today’s Groupon: for $125, you get a 3.5-hour dinner cruise for two on the Freeport Princess in Freeport (a $250 value). The cruise boards at 6:45 p.m. and sails from 7 p.m. to 10:30 p.m. on the following dates:

• Friday, October 21
• Friday, November 4
• Saturday, November 19
  
  

Captain Frank Rizzo and his crew draw on 35 years of navigation experience to pilot the Freeport Princess along the placid waters of Freeport’s Nautical Mile. On the night of their dinner cruise, passengers stroll up the gangplank of the 105-foot Coast Guard–certified yacht to wave kerchiefs at land-bound friends or don mermaid costumes and clamber onto the prow for luck. Once at sail, patrons can settle into plush stools and couches lining the main deck’s sumptuous windowed lounge, and slide past the cash bar for libations (not included in the dinner cruise) to toast the luxurious evening. The steaming buffet tempts diners with four gourmet appetizers and entrees in the formal dining area on the lower deck ringed with clear lucite tables to protect guests from having their shoelaces tied together while eating. Passengers can mount the elegant glassed-in stairs to the upper level, where DJs spin tunes on a large dance floor sparkling with disco lights and an outer deck lets passengers relish ocean breezes and peaceful views of the Nautical Mile’s cozy harbors.
