After I finished school, I worked for a few weeks on a converted sailing freighter in the Baltic, the Ewer "Petrine" (she was built in 1904, one of the first of it´s kind made of steel, a flat bottomed ship of about 36 meters total with two masts and side boards used back then for supplying farming communities on the islands in the North Sea and Baltic. Due to her having no keel she could be beached at low tide, so that the farmers could come out with horse carriages to load and unload the goods, back then bricks, fertilizer and timber to the islands and farm produce back to Hamburg etc.. This ship got a Danish Alpha diesel auxilary engine installed in 1936, 100 HP
at 300 RPM out of two cylinders!). I was taking care of the engine and doing general deckshand work. The owner had the ship converted for cruises by installing cabins and a big mess in the former cargo hold.
Funny thing was, we got some wind one day causing some swell. The skipper, his girlfriend and myself were the only ones who could stay below deck without getting sick.
