I don't think much shadow was added, but they shouldn't have used longitudinal barge reference dimension for perpendicular sub dimension.

They added the shadow to the diameter.

I respectfully disagree with respect to the shadow. Below is a version of the top pic in

To me, the top yellow arrowhead does indeed point to the hull edge itself, while the red arrowhead (added by me) points to the shadow edge. The red longitudinal line (added by me) approximately defines the shadow edge. The light-blue line (added by me) approximately defines the starboard hull edge.

I am *not* opining on whether the 14.249m approximation is accurate, however. I am opining *only* on whether the yellow line between the two yellow arrowheads includes the shadow.

Perhaps I misread how the line they drew works, with the arrow.

Oh, I think I see what you mean. It's possible that the attempted beam measurement in the original is between the tip of the lower yellow arrow and the *base* of the upper yellow arrowhead/triangle. I wouldn't do it that way (I think going "tip to tip" is more intuitive/less confusing than going "tip to base"), but there's no law against it, as the saying goes.

Wll if it really is 122m x 14m then the cylindrical volume is 18,780 cubic metres. Subtract a bit for both ends, add a smaller bit for the sail, say ~16kt submerged displacement? Vanguard class is 150m x 12.8m with that displacement.
