Monarch sailed 242 nautical miles in a single day, approaching HMS Ocean's reported 243-mile record. Ocean was a Prince Consort-class ironclad with an efficient hull, making her a useful comparison for Monarch's performance under sail. A difference of one mile was small against the uncertainty of measurements from the period. Using a rough margin of three percent either way, the two daily distances would be effectively indistinguishable. Monarch's fine hull had delivered a daily sailing distance comparable to Ocean's.
