I like very much the concept, and the tabs dividing categories are most useful
For warships I would leave just one per page, including "photographs" below the silhouette, and in the silhouette you could highlight with a red circle the most important characteristic of the ship which differentiates it from others, as is done in the real Weyer's Taschenbuch
Finally, if you could find a way to allow direct setting of the mast heigth in the stadimeter like the US boats interface currently allows, that would be the perfect complement
P.S. I forgot:
The Weyer's Taschenbuch has detailed info per ship divided by countries, and then also a set of tables with very small silhouettes ordered by ship class -all countries mixed together- so as to quickly identify first the ship and then get teh details.
