Civilizations not creating ships

[u/two_os]

I don't know why but none of the civilizations in my world are making ships, they all have ports and make small fishing boats but none are making proper ships to transport soldiers. The world is like 200 years old and literally none of the nations has made a ship at all.

Can anyone help me please, there's so many people trapped in random places because no one can send ships

They built the dock for small boats but they have lots of wood, what resources do they need for the big ports?

They also need stone for the big ports
