Hong Kong Marine Police

The Hong Kong Marine Police had a programme to replace 35 patrol boats that had previously been delivered between 1980 and 1992. The first to be replaced were the Damen Mk I class for which the ASC designed Keka class was chosen. They were built by Cheoy Lee Shipyards in Hong Kong and in their yard in mainland China between 2000 and 2005. They were ordered in two batches of two and four boats.^[3]
