Already with one eye turned towards spring, the New England Boat Show continues at the Boston Convention & Exhibition Center through February 19. Those who dream of heading out onto the water can point their rudders toward the Seaport District to get the inside scoop on brand-new sailing and motor vessels, as well as state-of-the-art accessories at the show’s more than 250 exhibits. Also experience daily seminars from industry experts on everything from how to cruise local waterways and engine maintenance to maritime safety tips and the latest in electronic navigation equipment. And that’s not all: there’s an interactive learning center, boating simulators, contests and giveaways, and an appearance by Dave Carraro from National Geographic Channel’s “Wicked Tuna” on February 13.
