I don't know anything about NC or Wilson but I am assuming you will moor your boat in Washington NC. On Google maps I don't see any body of water close to you for a trawler so I'm making the above assumption.
So I looked at where I would take my boat if I had it moored in the Washington NC area and of course all those lovely islands or whatever they're called pooped out. Also the distance from Washington to Hatteras looks substantial.
So I would suggest you abandon the whole trawler thing and look at Express Cruisers, the boat that can't get any respect. So a boat style I really like with a feature I think more and more boat manufactures will be copying is slide out seats in the cockpit area. If you look at the link provided, on the hull in the cockpit location you will notice a rectangle, that rectangle slides out and becomes a seat. These seats are on both sides of the boat so with guests at the dock you can comfortably have 6 guest with a table for your goodies set up.

Here's a video of said boat, pay attention to the spiel the reviewer gives on the philosophy of this boat. What he says is true in my local area on the other side of North America, big boats sit at the docks more than smaller boats. I think you'll like the creative use of the cockpit amenities. This boat gives you great control, decent speed, livability, good entertaining room, while saving money in moorage fees, more spaces available to you with a smaller boat, less servicing fees, etc.
For my area the Express Cruiser is the perfect compromise. Living close to excellent inlets and fjords, relatively "close" to Alaska, with the Gulf and San Juan Islands relatively "close" I want a boat that is just large enough so I can live comfortably on it over a period of time, but get into the area I want to be, then slow down to smell the roses, or kelp.
If you look at the models, the Cutwater 30 CB has a command bridge:

And I wouldn't recommend a diesel for this boat, I'll give you a link about engines, gas versus diesel. You will save money with gas, less vibration, less stink, less mess, less expense, no fuel polishing:

As much as I enjoy cruising along at slower speeds, 6-7 knots just ain't gonna cut it.
