This patch changes the following:
* Fishing boat construction time from 20 to 15 (biremes have 20, triremes 25, quinqueremes 30).
* Tweaked merchant ships:
* cost from 0 wood + 100 metal to 200150 wood + 100 metal (land traders cost 100 food + 80 metal);
* base trade gain increased by a third, from 0.75 to 1 (land traders have 0.75);
* movement speed is unchanged at ×1.35 (land traders have ×1);
* +50% health, from 400 to 600500 (land traders have 100);
* same armourdamage resistance as other ships (except fishing boats).
* Quinquereme population from 3 to 5 (biremes have 2, triremes 3).
* Warships get a 2:1 wood to metal cost:
* bireme from 125 wood + 50 metal to 120 wood + 60 metal;
* trireme from 150 wood + 150 metal to 24200 wood + 1200 metal;al (also for kush);
* quinquereme from 350 wood + 350 stone + 200 metal to 5600 wood + 25300 metal;
* juggernaut from 400 wood + 350 stone + 300 metal to 800 wood + 400 metal.
* Ship loot is standardized to 120% of costs, similar to other unitssiege engines and structures.
* Removed <xp>* Ship <xp> loot is standardized to 10% of their health, but removed from fishing boat and merchant ship, since they can't attack.
Because merchantmen have a third more trade gainmovement speed, a thirda lot more movement speedhealth, and a lot more health and armourresistance, and trade routes become far more profitable the longer the distance, as consequence garrisoning land traders in merchant ships might become an interesting option in some special cases (#3428).
