Could continual repainting explain why Hood sat lower in the water?
Short answerIt would require an enormous quantity of paint. Wartime water in torpedo-defence spaces is a more plausible explanation, although the cited book passage remains unchecked.
NotesA viewer attributes the paint explanation to Bruce Taylor's book on Hood, whose wording remains unchecked during the exchange. Making a ship of roughly 42,000 tons sit appreciably lower would require an enormous weight of paint, even with lead-based coatings. Wartime water carried in torpedo-defence spaces could increase draught and resistance, whereas leaving those spaces unfilled in peacetime would reduce the burden on propulsion. Nelson and Rodney provide a comparison: discharging water could lighten them and increase speed. Paint also disappeared through chipping and salt-water exposure, so repainting did not simply add an uninterrupted succession of layers. The proposed explanation remains a judgment about the relative weights involved, with the book's precise claim unresolved.
