You really don't even have to use the piers to be honest. Just look at the light poles. They are slightly further apart in the cutter photo and slightly closer together in the mystery hull photo. This clearly indicates that the cutter photographer needs to shift left to match angles with the mystery hull photo. Once we establish the same distance from the hulls for both photographers, the fact that the cutter photographer has to then shift left is more than enough to establish that the cutter's beam is dramatically wider than the mystery hull's beam.
I thought about using the light poles, but the massive black words "da xin wen" make it a bit hard to easily tell where they all are relative to each other. It's also hard to tell where the light poles are using satellite because they're so small, so it's in turn more difficult to tell how the increase in space between light poles will affect the beam of the ship when we don't know their exact orientation relative to ship beam.
But it's alright, I think I found a better picture which shows that something is up with the perspective of the two photos...
However first, here is a picture which demonstrates that the previous distance between the concrete pier and the blue gate was a poor one:
basically, the entire "left side" (from our POV) of each column for the concrete pier appears larger because I think the cutter photo was taken sometime early in the morning when the sun was rising from the east, which helped to illuminate the entire "left side" of each column. Combined with the blurred effect of the bottom of the photo for the cutter photo, it creates a sense that that is a major difference in visual distance, when there probably isn't.
My bad for using a poor example, and wasting everyone's time.

Now, for the better picture, which is unaffected by difference in sunlight, and unaffected by blur -- I chose the distance between the edge of the white building and the crack on the white building.
The (left) edge of the white building is lined up with a thin red line, and the purple arrows indicate the crack in the surface of the white building.
We can see that the length is far greater in the cutter photograph than the suspected 055 module photo.
A more detailed comparison using only the building's width (ignoring height, which is irrelevant for this comparison), and lined up more closely, shows the same:
Another good thing about using the building as a benchmark is that the front surface of the building was parallel with the measured beam of the cutter in the graving dock (as seen below with the photo below -- there are thin red lines of the building's surface and the cutter's beam to show they are indeed parallel)... and it should probably also be parallel with the beam of the potential 055 module in the same graving dock.
That means, any change in perspective which causes an increase or decrease in visual distance of the building's edge to the building's crack, would likely have a similar effect on the visual distance of the beam of the ship in that graving dock, because the distance we're interested in should be parallel with the metric distance of the building edge to building crack which we're using (accounting for any differences in relative proximity between each ship in the graving dock and the building, which will also have an effect)
Therefore, using the distance between the white building's edge and the crack in the building, I think it is reasonable to argue that there is something about the cutter's photo which may have increased the beam of the cutter relative to the beam of the potential 055 module, between the two pictures, possibly the photographer in the cutter photo stood more to the left relative to the module photo where the photographer was more right.
That said, I'm a little bit confused as to how there can be such a significant difference in the length of the building edge to building crack between the two photos, while there is such a small difference between the previous visual distance we measured (concrete pier to blue gate -- once we compensate for the sun and the blur)....
So, overall I think the difference in the building's we have enough perspective effects/artefacts to say that something is definitely up, and that using the photos as they are to try and guess the potential 055 module's beam relative to the cutter is not as simple as a cut and paste.
I do think that it's probably too much for me to say that the potential 055 module is probably greater in beam than the cutter, because even accounting for perspective distortions and angles, it is hard to be confident in saying that, so I'll take back my previous statement in that regard.
However, at the same time, I also don't think we can be anywhere near confident enough with the evidence we have at hand to say that the modules definitively cannot be for the 055 as a result of its suspected beam, due to the effect of perspective/angle.
Better for us to wait for satellite photos, which I'm sure we'll get in a few months.
