See the Benjamin Franklin Bridge from a yacht (supplies limited). Splash past a submarine in a kayak, swan boat, row boat or skiff. Then explore the shore, where two dozen marine-themed exhibitors will greet you — with giveaways. These and other attractions will make Pennsylvania’s coast come alive outside the Independence Seaport Museum.
