Situ Jiacheng explained on the radio program "Millennium Times" that in general, even if the boat is anchored, it will maintain its power to resist the wind and waves. However, the structure of the boat has a buoyancy tank, which is filled with water as a balance point to balance the left and right sides. , but once the power is lost, the anchor chain will be disconnected due to the pressure of wind and water, and the hull will be thrown up.

Three people in the accident were rescued by the Hong Kong Flying Service helicopter and sent to the hospital.

He continued that there was a wind farm near the scene, and the windmill was 800 feet high. The helicopter had to avoid the windmill and fly to a height of 1,500 feet and enter the clouds before it could drop the flight height, describing it as very difficult to rescue.
