Regarding the seascape. I honestly do not know if I can pull it off to my liking but I am gonna try. You don't grow if your don't push your boundaries.
Never know until you try.
While the hull is in its raw state right now, it might be a good time to sort out making a mould of same. This could allow for experimenting with various seascaping. (Returning a bit, to the UK fellow in the fine article above.)
Or not. Life is like that.
On lighting the cabin. Prototypically, wheelhouse was kept dim so that the windows would not be opaque black in the night. But, that level of realsm woud be durst hard to model.
So, a low, amber sort o glow might be the right answer.
Fishermen go where the fish are, which might not be the most comfortable climes. Cold and damp are often the rule. So, an over-warm pilothouse with fogged-over glass is entirely appropriate. Frosted to opaque could be seen as splitting hairs.
Proably ought box in some of the house portholes so that they sho a mix of lighting. Bright white lights would be in use below decks. Back in the day, that lighting would be Edison lamps.
While on lighting, underway, our trawler ought show red & green navigation lights, brobably back on the wheelhouse (they are meant to be visible from straight ahead around to the beam on either side).
She will need a stern light either at the end of the house structure or at the stern rail. This wil lbe visible 45° either side of dead aft.
The foremast will want a white light visible 180° from port bram to forward, to starboard beam.
Trawlers will show a green or red light (360°) with a white (360°) light over it (6' above typically). They also have a 360° masthead light on the after mast. They ought have another white light--6' vertical separation-- on the after mast.
If modeing from the 70s onward, there should be all manner of flood lights illuminating the working deck (think used-car lot lights at Ballpark levels of illumination). This could be compicated to model.
Oh, and I was reminded that such a trawler would, in all eras, have an ice machine aboard. In early days that would be an ammonia or methanol plant (which would need some exhaust stacks). Later plants would be more conventionally refrigerated.
