The general shape of the Nelson Decanter came about in the second half of the 18th Century, developed by a British admiral, by the name of Rodney. He introduced one at the victory celebration on board his flagship following the famous Moonlight battle and the battle of the saints in 1780 and 1782. The decanter had a very broad base, up to 12 inches in diameter, to ensure stability when at sea. The Rodney test is when the shortest distance from the outer edge of the pouring lip to the edge of the base, be equal to or greater than the outer circumference of the pouring lip.
