Help the National Maritime Museum to celebrate the opening of their Ships, Clocks and Stars exhibition at this late opening packed with sea-themed silliness. Shore Leave's drunken sailor party will provide a cabaret and promenade performance and the museum's curators will be challenged to present 20 slides in under 20 seconds a slide – if they fail they'll have to walk the plank. Dark and stormy rum cocktails will be available, and free beers from Meantime Brewery will keep cogs turning during the pub quiz. Tickets include entry to the exhibition. Book in advance.
