Protection, broadside guns, and sail endurance

Waterline protection around the machinery anticipates the later use of armour decks to protect spaces that kept a ship afloat and mobile. Her guns were arranged for broadside fighting. A brief comparison with science-fiction warships notes how often they borrow age-of-sail broadside imagery even when their fictional engineering does not impose the same constraints. Nelson's masts remained useful because sail offered self-reliance on a distant station and helped avoid the political embarrassment of a flagship immobilised by machinery trouble. An admiral could present an arrival under canvas as preference or seamanship, preserving the ship's public image even if the steam machinery was unavailable.
