A series of accidents are happening as the number of people participating in marine leisure sports is increasing.
Last year, 469 accidents occurred involving water leisure equipment, and a series of crashes, capsizes, and drifts have already occurred this year.
According to the Korea Marina Association, there are nearly 25,000 registered leisure boats as of December 2017.
Experts advise users to wear proper safety equipment and strictly abide by safety standards prior to going on the ocean.
Busan Coast Guard has also created the first on-the-water patrol team to prevent such accidents.
