Few months ago using real Blueprints for most accurate scale I build RMS Titanic using Richlarrousse Design ( link to his youtube channel is here :https://www.youtube.com/channel/UCrVKIhnZHZcl8eHEucLOzYw ) only upscaling it with quite few imperfections . Its missing a lot of details so it give you opportunity using real blueprints of decks make it as realistic as possible.
If you share passion for ships and love Titanic like I do here you are I hope you will like it
