Rearranged boiler rooms originally exhausted through one enormous trunked funnel. Later machinery changes produced the two-funnel silhouette shown in the lecture. The original form is compared to a Japanese-style funnel on a British-style hull. That visual distinction came at a cost because the trunking added weight and complicated power generation. Superstructure appearance can reveal the machinery layout and compromises beneath it.

What the enormous original funnel cost the design
The class's original single-funnel arrangement turned machinery routing and visual distinctiveness into a weight-and-efficiency trade-off.
