For $9, today's side deal gets you a three-day pass to the Lake Union Boats Afloat Show, taking place Sept. 15–19 from 10 a.m. to 6 p.m. daily (an $18 value). The show will be at South Lake Union at Chandler's Cove, 901 Fairview Avenue North.

Now in its 32nd year, the Lake Union Boats Afloat Show gives guests the chance to check out hundreds of seaworthy craft, including sailboats, yachts, and trawlers. The more than 50 brands of yachts on display will include Bayliner, Westport, and Sunseeker, with roughly 30 vendors of insurance, maintenance, and other supplemental services on hand to help boat owners protect their investment. Attendees will also get to climb aboard and inspect the 64-foot Ocean Watch—which circumnavigated the Americas for a year in support of oceanic health—and discuss the epic voyage with the crew, as well as take part in interactive activities.
