Thats a good question. HMS Juno took me about a month, but i mostly just work on these in my lunch breaks at work. I have a small baby, so don't get much time at home to build these. i do occasionally head into work early in the mornings to get a little more work done on the ships, which helps. Im guessing this is going to take a couple of months to complete, though i might be way off with this prediction.
