Having found the vast majority of galleons and other ships already posted to PMC far far too big for the other structures I've built I made the attempt to build a pair of ships that were more more proportionate with the timely help of the "spanish galleon walkthrough" by Sillouete (Thank you it was incredibly helpful!!) www.planetminecraft.com/blog/walk-trough-of-a-spanish-galleon/

Ship dimensions are: length 59 blocks, height 52 blocks. Hope I didn't do too badly for my first attempt!!
