For those of us that are interested in Naval history, choosing a ship based on a historical perspective is a big part of the process. The story of the battle of Jutland is popular with many of our captains, and there are many models of ships that participated in the battle in our hobby today. The battle of Guadalcanal and Ironbottom sound is another great story that includes many ships that we use today. The battle of the Denmark Strait has resulted in the Prinz Eugen, Bismarck, and Hood being built more than others. I have the SMS Baden (Bayern Class) which at its time was the most powerful dreadnought battleship on the water.
This is a great place to start your search as you can make a list of your ships of interest and take them down the list of other decision perspectives until you pick the right one.
