594 studs long is absolutely HUGE considering it's only 179 feet.
if we are to compare the height of a blockhead to the height of a IRL person, a meter in blockland is somewhere in the ballpark of 3 to 4 studs in length. this means a 6x height cieling is around 2 meters in height (depending on how you measure it), which is a comfortable standard for blockheads.
knowing that, a 594-stud long ship would be between 148 to 198 meters in length, or 485 - 649 feet, which is around THREE TIMES as big as the original ship you are basing this build on.
i'd simply advise you to be careful when it comes to scaling, because otherwise the blockheads are gonna look super tiny on this ship if you are building it to the same proportions for windows, doors, decks and stairs. it'd be like alice in wonderland. If you continue building it at a ~600 stud length scale, it's going to be very difficult for players to really navigate the build without being supersized to fit in the huge doorways and openings (unless you plan on making the actual ship interior simply of your own custom design that fits blockheads, which would be cool but would also be very inaccurate in respect to the size of the actual ship).
i've done some calculations, and here are some ballpark ranges for a more appropiate length of your ship when scaling to blockheads in blockland.
Your vessel would be 54.7 meters in length (rounded to the nearest tenth) when converted to metric from its real life length of 179.5'. When it comes to a 3-4 stud length meter ballpark, that would mean your ship would scale well with blockheads when built between 164 - 219 studs in length. I'd personally recommend building it at 219 studs length because that's generally going to both allow the build to be big enough for blockheads to have plenty of cieling space, while also not being TOO big.
Hope this helps. Scaling is a big issue for me myself when I build Star Trek ships.
