What puzzles me is why you think a starship construction area is much like a water ship one. Building one is not like building the other.
Just because they're labelled "shipyards" and the two almost totally different types of vessel are both called ships? That's illogical.
In any case... my main point was not as much how they're put together, but that unlike watercraft but very much like aircraft, you can't just vary the dimensions from unit to unit. If a water ferry is built a metre longer than a sister ship, it's not going to be a big issue most of the time. Two different shipyards can and will construct similar but not identical ships of a class. If you significantly alter the dimensions of an aircraft or spacecraft, it's a deliberate design decision that's going to immediately affect its performance and will need a full range of testing.
A ship whose speed turns out to be a bit slower than expected is an annoyance. Aircraft (and spacecraft) which don't meet design specs are hazards.
And having said all that, I fully accept that there will be type variations in starship hulls... but those won't be accidental or casual. If a variation IS fully tested and practical, add that to the standard plans once it's approved.
