This is the low-tech version of what started as an airship design: www.planetminecraft.com/project/airship-fleet-viking-longship/

Since that one was more of a boat with add-ons, I thought I would also upload a version for people playing medieval instead of steampunk. I removed the iron from the schematic and moved a few other things around. It wasn't really designed for this, though, so it isn't really accurate in some respects.

Since this is a ship, I couldn't resist using the Water Shader mod for the screenshots. Makes everything look much nicer...
