Tugboat Near Koh Samui Hits Rocks, Minor Damage — Tourists Safe

On the morning of Thursday, July 9, 2026, a tugboat struck rocks off the coast of Koh Samui, Surat Thani. The incident occurred in the western channel of the island, about 1.2 nautical miles from shore. Witnesses reported the boat hit the rocks while attempting to tow a tourist vessel toward the pier in light wind and wave conditions. Local rescue teams and marine patrol officers immediately went to the scene to assess the situation and provide initial assistance.

According to the navy and the coastal defense unit, the medium-sized tug sustained damage to its stern and sections of the hull, with visible scrapes and cracks in the steel plating, but it did not sink. All passengers — tourists who had been being towed from the original tour boat — were confirmed uninjured and were able to return to shore with the help of the tug and other local boats that arrived before rescue crews.

Local officials said that although there were no injuries in this incident, a serious accident could have occurred if towing operations had not followed safety standards, especially in areas with submerged rocks and shifting sandbanks affected by currents. Port authorities and the Marine Safety Control Center have stepped up inspections of charter and towing operations and have summoned the vessel owner and the chief of the crew to report for an investigation into the true cause of the grounding.

Short-term impacts on tourism on Koh Samui remain limited because the incident happened offshore and did not affect the main piers. However, shops offering diving trips and boat charters reported that some customers are more concerned and are increasingly asking about safety measures before booking trips. Koh Samui municipal tourism officials said they will increase public information about maritime safety measures and urge operators to submit emergency operation plans to reassure tourists.

At the same time, local fishing communities nearby have called for additional warning markers and navigation buoys at the hazardous offshore spots, noting that the seafloor in the area has rocks and sandbanks that shift with currents. Marine tour operators agreed and proposed mandatory safety and sea-rescue training for all crew members. Authorities have ordered urgent repairs to the damaged vessel and inspections of all boats before they head out to sea.

Officials will continue investigating the cause of the grounding, reviewing voyage logs, weather conditions at the time, the readiness of navigation equipment, and the crew’s competence. If serious lapses are found, legal action under maritime law may follow to prevent future incidents. Meanwhile, tourism agencies will work with local operators to reinforce safety standards and continuous emergency preparedness to protect both visitors and Koh Samui residents.
