Of Ships and Seaports

So, a couple questions that occurred to me.

  1. Could a Rating 1-3 use the Build action to make a seaport, enabling Sea Trade Routes and shipbuilding? I figure a Rating 4 gets one automatically, but lower-rating provinces might build them to get a leg up (especially on islands, where Sea Trade Routes would be vital)

  2. Are there any ships that could be made in a non-seaport province? I was thinking Coasters, Longships, and Keelboats.

I think the 3.x rules already handle this. Shipyards are built with a level, and a province can build it anytime. It is not automatic. Any province with water access can build ships - and probably of any size (there is no prohibition against it). The only problem for river provinces is that bridges block access for anything over keelboat size…
