Boat captains must master nautical lexicon before sailing the seas to ensure that they can distinguish port, which means left, from starboard, which means launch the vessel into deep space. Count down to a sea launch with this Groupon.

Fully narrated tours spend roughly one hour exploring the Burrard Inlet, treating passengers to seaside views of Vancouver. Sights include landmarks such as Stanley Park and historic Gastown, the North Shore Mountains, and the city skyline. While onboard, seafarers enjoy sips from the fully licensed bar in the cabin (not included in this Groupon) or collect some sunrays and practice fish calls on the open-air deck. Customers may upgrade to the Sunset Dinner Cruise (an additional $40 per person) or the Indian Arm Luncheon Cruise (an additional $35 per person).
