The Vinnen 5 masters were a very queer batch of ships owned by Alfred Vinnen and Co. of Germany.
These strange ships were each about 150 feet long. On their foremast, square sails. On their middle mast, square sails. The rest of the masts and the bowsprit were all fore and aft or gaff rigged. They were cluumsy, a pain in the but to handle, and often wrecked. Indeed, at least 85% of them were wrecked on rocks in 2 or fewer years. Older sailors, who hated these craft, called them "5 masted bastards", because they looked nothing like older sailing ships.
