SAIL ROCK - GMI
A rocky Great Mercury pinnacle with kelp, sand, and strong exposure.
Boat-access reef at Great Mercury Island with a shallow top, channels, and a weather-sensitive north face.
About SAIL ROCK - GMI
A rocky pinnacle on the Great Mercury side with kelp-covered reef, sandy transitions, and a route that stays easy to read when the weather is kind. The top is shallow enough to feel friendly, but the northern face can be heavily wind- and swell-exposed, so the dive works best as a planned boat run. Fish life and color are the draw, with porcupinefish, reef fish, and rocky structure making it rewarding for experienced local divers.
