adding new units to normal ai

[turtlelink2]

HI, ai is so complicated and when i tryed to do it i just created errors, what I am trying to do is make a sea map, theres a second peon/wisp ect. that can build a shipyard witch trains boats, but they will never use them. I just want the normal ai but they use the boats too. the boats are a transport ship, a frigitt and a battle ship, please help =)
