[Trigger] How To Get Triggered AI To Build On Water?

[Darkness-4ever]

Pretty much the title, I'm trying to trigger an AI to be able to build certain naval units on water terrain, but it either simply skips this or just jumps straight to the next building I have triggered for it, regardless of how close its builder is to the water. The method I use to make it build structures on land is quite simplistic, so I'm wondering if anyone can give some advice on how to make it able to detect, and then build naval structures if there is water nearby.
Thanks in advance.

I would try finding a costal point from their base and then tracing it back till they find land. Then keep searching around till a place that suits construction is found.

If your map as few buildable water areas, hard code the positions and get the AI to search from them.
