For 30 years the Blue Riband has been held by fast catamaran ferries made by companies like Incat and Austal that can travel at over 40 knots for sustained periods. While they're not traditional liners, they are passenger ships and some of them are quite large, they be up to 12,000 Gross Tons. So nuclear subs are not the fastest ships.

@stevek8829 Well if you want to go for the ship capable of the highest speed for sustained periods, it's Francisco, an Incat fast ferry. At 99 metres, it's smaller than a lot of their ships, but it has reached 58 knots and can hold 50 knots for long periods. Built in Tasmania and operates in South America, it has crossed the Pacific, but not the Atlantic. https://en.wikipedia.org/wiki/HSC_Francisco
