Hi
Not a maritime museum (though Liverpool has a great one) but a hotel with a prow that faces the Mersey. When it was first built (seventies?) it was quite an exciting addition to the waterfront: and in those days it wasn't hemmed in either side by those two modern buildings. I remember the hotel had a parrot in one of the bars, it was partial to a wee nip of the hard stuff - great fun. There is also to the far left the absolute monstrosity that is the Liverpool Daily Post and Echo Offices.
If you ever get to Liverpool don't miss a 2 minute walk through the ground floor of the Port of Liverpool Building - a fantastic bit of architecture looking up into the dome. It's on the waterfront so it's handy for The Albert Dock, The Maritime Museum, Merset Ferries, etc
