Shipping routes progress in danger over time from safe (green), hazardous (yellow), dangerous (orange), to treacherous (red). Enemy ships don't seem to benefit from these bonuses. Up to 3 can ships be used to battle and clear a route, with the top ship gaining a speed bonus, the middle gaining power, and the bottom gaining defense. During battle you can also lauch fire barrels to deal extra damage to enemy ships, although you only have a finite supply (more are gained from additional battles). You will then watch the battle and, if you win, you will get the resources needed to perform missions. You can then choose the ships you wish to use to do battle. This also reduces a route's danger level making successful missions more likely.

You need resources (cargo) to carry out missions, and you can gain resources by battling other ships on routes.
