The fastest fish in the ocean — 110 km/h — hunting baitballs in Mexico's open Atlantic. The most adrenalised in-water encounter you can have without baited sharks.
This guide covers the 2 best places in the world to encounter sailfish from a liveaboard, when to go, what to expect underwater, and how to behave in the water so the encounter is as good for the animal as it is for you. Every recommendation comes from operators who run these dives weekly — not from textbooks.
