Dive Briefing

"The dive boat departs from Alibaug harbour for the 15-minute crossing to the reef flat near Korlai Fort. Enter the water into calm shallow conditions with the rocky reef visible below at approximately 5 metres. Swim over the rocky formations observing parrotfish grazing on algae-covered rocks and damselfish defending their territories. Navigate to crevices where moray eels extend their heads and rocky surfaces where nudibranchs display their colourful patterns. The sandy patches between rock formations host sea cucumbers and various invertebrates. The shallow depth provides extended bottom times exceeding 50 minutes. Ascend directly to the boat through calm surface conditions with Korlai Fort visible onshore. The return crossing provides time to review photographs and discuss marine species observed while planning progression to deeper sites further from Mumbai for more diverse diving experiences. Safety procedures include establishing maximum depth limits and bottom time constraints to ensure conservative diving practices near the busy shipping channel."
