Started work on the Yamato last night. Based on what I've found, one block is approximately 1 meter, cubed. Yamato is 256 meters long (at the waterline, a bit longer from the top of the bow to the stern) and 39 meters wide. I've actually had to spend most of my time carving out a harbor big enough to support this thing and I actually have a lot of infrastructure to go before I start laying the keel. I'm shocked at how big that beast was and even more shocked at how they got it to float! I'll post pictures when I start making some real progress.
