Germany is adjacent to the North Sea. Poland is east of Germany, away from the North Sea. The Baltic Sea is adjacent on the north to both Germany & Poland. Germany would not need to go through Poland to get to the North Sea or the the Baltic Sea. However, the Polish navy in 1939 sent ships from the Baltic Sea to the North Sea by traveling west and north past Germany, and around Denmark. Or you may be thinking about the fact that in 1939 before WW2 started that Poland had a sliver of land called the Danzig corridor (by the Germans) that connected Poland to the Baltic Sea. However this piece of Poland cut through the old WW1 Germany boundaries, causing Germany's East Prussia to be separated on land from the rest of Germany. Look at a 1919-1939 map of Europe.
According to a map located on the CIA World Fact Book, the only two major bodies of water located IN Poland are the Vistula and the Oder River. The Vistula runs from the SW corner near the border of the Czech Republic into central Poland, running through Warsaw, the capitol, and then emptying into the Baltic Sea in the North. The Oder starts in the Czech Republic and runs into western Poland before running along the Poland/German border around Frankfurt and then runs into the Baltic Sea. These are the two "major" bodies of water recognized by the CIA, however there are several small lakes and rivers located in Poland.
