Making waves

I enjoyed your Gone But Not Forgotten item on MacSweney’s patent jointed ship from July 1856, which was designed to allow a ship to rise with the waves.


I enjoyed your Gone But Not Forgotten item on MacSweney’s patent jointed ship from July 1856, which was designed to allow a ship to rise with the waves (Back Page, 3 September).

Earlier this year in The Big Picture you featured Proteus, another vessel that can adapt its movements to the sea’s surface.

It caught my eye because one of my own designs, Catapult, launched some 25 years ago, like Proteus used inflatable hulls and might have been an ideal subject for the magazine at the time.
