The salty sea air, the stars sparkling off the water, and the city behind you. It's time for another season of Boston Harbor Cruises. The vessels, which have been hitting the harbor since 1926 are great for those looking to grab a few drinks, see some bands, or dance the night away on the water. Those looking to spice up their Friday nights should book a ticket for their Salsa and Latin Cruise where 300-450 people converge to twist and shout. General admission tickets are $24 at the dock, $19 in advance, and group discounts are available.
