So, I have a place I tend to build my boats.  I’ve build maybe 2 in this spot, but I like it.  I was working today on a barracuda vessel to test the submarine requirements, and it kept saying my block count was too low.  I figure that’s probably true so I wind up adding a BUNCH more blocks, over 4 stacks in addition to the original design.  It still says not enough.  So, as a sanity check, and to see where I’m at, I try registering as a dhow.  Too few blocks again.  Tried registering a wall on the structure I build in, too small.  Try registering an actual Dhow I own, works fine.  Tried registering my house: forbidden blocks, but not too small.  Tried my new creation again, too small for even a Dhow.  Do subs not work anymore?  Am I doing it wrong? No matter what it says it’s too small for a dhow, let alone a barracuda.
