Although this marine heritage center at the south end of Lake Union is currently little more than a shipyard for the restoration of four historic ships, it has grand plans for the future. If you're a fan of tall ships and the age of sailing, you can pay a visit to the 1897 schooner Wawona, which is currently under restoration. Also being restored are a 1904 lightship, an 1889 tugboat, and a 1933 salmon troller. Throughout the year, there are folk music concerts ($10 adults, $7 seniors and children) on the deck of the Wawona (call for details), and on the second Friday of each month, there's a free Chantey Sing from 8 to 10pm. Nearby, at Chandler's Cove (901 Fairview Ave. N), you'll find the gift shop and the few small exhibits of the Puget Sound Maritime Historical Society (tel. 206/624-3028).
