Marine Region

The marine police patrols 1,651 km2 (637 sq mi) of waters within the territory of Hong Kong, including 263 islands.

It has a fleet of 142 boats in total, the largest of any civil police force in the world.

[3][4][5] The Marine Region comprises approximately 3,000 officers overseeing around 13,000 local craft and a total maritime population of 14,100.

[6] The Marine Region usually mounts shore patrol to police the smaller islands and isolated communities with no land transport to other parts of the Hong Kong, and participates in the Hong Kong Maritime Rescue Co-ordination Centre, which is responsible for co-ordinating maritime rescue operations both within and outside Hong Kong waters.

[13] As part of the response to the 2019–2020 Hong Kong protests, the Marine Police participated in Operation Tiderider aimed at quelling the ensuing riots.
