Engine Room
With hydraulic or electrical drive, the engine can be bedded in any convenient spot. It doesn’t have to be inline with the prop shaft. This enlarges the space for the accommodation, and allows more variety in layouts.

The trade-off is that the drive system is more expensive, from $20,000 to $50,000, and the larger accommodation increases the fitting out cost. So the trawler is substantially more expensive to build. Repair expertise is harder to find for hydraulic and electric drives; although construction and farming use hydraulic extensively.
The main trade-off is in the position of the galley, especially if it has cold-plate refrigeration. A cold-plate refrigerator should be as close as possible to the engine room.
