Sailing in a Special Area of The Great Barrier Reef and Torres Strait with Reef Pilot in Restricted Visibility

Navigating the Great Barrier Reef and Torres Strait presents a unique challenge in Restricted visibility conditions. Limited depth of the water heightens the risk of grounding. Additionally, Reduced sightlines heighten the risk of collisions with submerged hazards and other vessels. This study explores manoeuvring techniques for safe passage in these special areas. Through a combination of calculations of (squat, UKC, safe passing distance and safe speed), observations, and interviews with experienced mariners, the research identifies potential obstacles and corresponding manoeuvring strategies. Emphasis is placed on adhering to international regulations (COLREGs) and best practices (SOLAS, STCW) to ensure the safety of both the crew and the fragile marine ecosystem. Effective bridge team communication and familiarity with navigational equipment are crucial for successful manoeuvring during restricted visibility. Strict adherence to company policies further minimizes risks. This research offers valuable insights for mariners navigating these critical areas, promoting both environmental protection and crew safety.
