Sail Ships

This is a casual, 3D game with ship battles.
The purpose of the game is to reach the 12 levels of development (12 ship types). Advancing in development, ship types are getting bigger and stronger.
More and more silver is needed for development, which can be obtained in two ways:
- defeating enemy ships
- trading (you can buy and sell goods in different ports at different prices, you can get more silver from buying goods cheaply and selling it costly in another port)
There is a world map showing the ports (with prices), the position of some enemy ships, and the position of your own ship (with the points of the compass).
You can use a compass and a world map to determine the way you reach the ports and the (displayed) enemy ships.
The world map will only show you the position of your ship and your opponents, if it is prompted by pressing a key. You have a limited number of queries, which is reduced for each query, but you get new ones by defeating enemy ships. Worth to count this for good navigation.
