In the last photo you may notice what appear to be cable hawsers under the stern roller, these are actually drains for the roller compartment, on the actual vessel this is a series of 5 vents, I used 3 oversize to make sure it drains any water away quickly, the roller box being sealed from the rest of the hull.
Next photo is the beginning of adding detail to the forecastle deck, bulwark supports, snorkel vents, etc. The next two are for your opinions. I bought a commercial winch for the twin anchor chains and warping drums. Although to scale it just looks too small, however putting a 1/72nd figure next to it, and the winch is over head height, just a weird optical illusion. The winch isn't attached just placed their for you to give opinion on.
