Initial estimates indicate that some 2,924 square metres, more than 1.8 rai, of corals were affected by the foundering boat, the DMCR reported yesterday (Aug 20).
It is believed that the rusting hulk of the boat had drifted off its mooring off Koh Tapao Yai and became stranded on the reef at low tide.
The preliminary survey of the corals on Friday (Aug 18) found many different types of corals had suffered damage. There were deep cuts into the reef that may have been formed by the boat’s propeller. Broken corals from the sea floor were found scattered across the top of live corals.
Of the corals damaged by the boat were dwarf corals, ringed corals and long-grooved brain corals, as well as honeycomb corals, among others.
The DMCR is continuing its survey. So far no mention has been made of any action against the owner of the derelict boat.
