The largest regularly built ship scale is served by paint masks at 1:200. Deck masking sheets for battleships such as Mikasa and Hood cover the broad planked areas while you spray the non-slip surfaces, and there are also stencils for spraying an ensign directly onto the deck. Every item names the exact kit release it is cut for, which matters here more than at any smaller size.
1:200 repays careful masking like no other scale: the deck is the size of your palm and any bleed would be glaringly obvious. Pick the stencil by the catalogue number of the kit you are building and spray thin coats through it. The hulls themselves are in 1:200 ship model kits, the full stencil index is at ship paint masks, and spraying non-slip areas goes hand in hand with a 1:200 wooden deck.
