Fastest fish in the ocean. Hunts sardine bait balls in coordinated teams — and the dorsal sail is the showpiece.

About sailfish

Sailfish are pelagic billfish — long bill, electric-blue iridescent body, and an enormous dorsal 'sail' they raise during high-speed bursts (up to 110 km/h, the fastest verified fish speed). They're warm-blooded around the eye and brain for sharper vision at depth.

The bucket-list encounter is Isla Mujeres (Mexico) — sailfish work together to herd sardine bait balls to the surface, then take turns striking the school. Snorkellers (not scuba — bubbles spook them) are dropped in the bait ball for some of the most dramatic underwater encounters anywhere on Earth.

From our region: Red Sea liveaboards occasionally encounter sailfish during open-water transits. Sri Lanka and Mozambique have offshore charter encounters during their respective sardine-run seasons. Dedicated sailfish trips remain a Mexico or Costa Rica affair.

Frequently asked questions

When is the best time to dive with sailfish?
Isla Mujeres Dec–Mar. Costa Rica Pacific year-round. Red Sea opportunistic on Brothers transits.
What's the best destination for first-timers?
Mauritius is the easiest entry point — short flights, beginner-friendly conditions, and reliable sightings during peak months.
What certification do I need?
Yes — Advanced Open Water (or equivalent) is strongly recommended. Sightings happen at depth (often 25–40m) or in current. PADI/SSI Advanced certification is the gateway, plus 20+ logged dives.
Photography tips?
Snorkel, fast shutter (1/500+). The raised sail and metallic-blue colour are the icon shots — both vanish in the wrong light.
