I admit, this is probably stretching the term ‘bench’ rather far!
Falmouth’s National Maritime Museum has an amazing display of boats suspended from the ceiling so they look like they’re floating in the air. If that wasn’t bizarrely wonderful enough, there’s a surprise when you look through the boats at a certain point. This mannequin looks very real at first sight!
Work on the trapeze when sailing requires fitness and skill. I’m not a great sailor (having spent more time windsurfing) but I loved it on there, arched over the water with nothing but your feet on the boat, your stomach muscles working full time and the wire above keeping you from falling in the water!
