my hometown (hamburg) used to be the major homeport for germany's whaling fleet from the 16th century right up to WW II .
i still remember seing the whalers(the motherships) and the hunters (smaller boats that would hunt the whales , harpoon them and tow them to the mothership) coming back into port after the whaling season .
this picture was done BEFORE my time
hunter
note the "bucket" at the top of the mast where the "whalespotter" would be on the lookout for whales .
the harpoon cannon is located on the bow .
