Warrior versus Monitor: sea room decides the fight

Could USS Monitor defeat HMS Warrior? The answer distinguishes a surprise in confined water from an open-ocean encounter.

Question

How would an 1861 fight between HMS Warrior and USS Monitor likely unfold?

Short answer

Monitor might prevail in a rare surprise attack in sheltered water, but Warrior's speed and ocean-going qualities would give Britain the stronger position in the open sea.

Notes

Monitor might gain an opportunity by surprising Warrior in an undefended harbour at night and obtaining early raking shots. In open water Warrior’s cruising speed was nearly twice Monitor’s maximum, allowing the British ship to control range and bearing. Monitor’s powerful guns and turret were dangerous, but low freeboard and a coastal design made rough water a threat before battle even began. Warrior could circle, keep her broadside bearing, and fire without accepting the close engagement Monitor needed. Ramming would add needless risk when speed and sea room already gave the British ship the stronger tactical position.
