A pair of 24-meter catamaran patrol boats has been delivered to the Royal Thai Police. Designed by Incat Crowther and built by the Bangkok based Seacrest Marine, delivery of the vessels closes a capability gap identified by the police force.

The aluminum newbuilds, Ratayapibanbancha and Arcarachwaratorn, are based on the Reef Ranger designed by Incat Crowther and commenced operation as a patrol boat on Australia’s Great Barrier Reef in 2014. According to the designer, the platform has demonstrated superior operating characteristics in service and was identified as capable of meeting the mission demanded by the Royal Thai Police.

A large aft working deck houses a 4.5-meter fast rescue craft, forward of which is the main deck cabin. The cabin has a fully-featured galley to starboard and a wet room to port. Forward of the hull access are two large rooms, one a dormitory for 8 crew, the other a large mess and dining space.

Upstairs are two large cabins with ensuites for senior officers in addition to a private living area. The wheelhouse features a lounge and forward-raked windows affording excellent visibility. Doors from the wheelhouse provide direct access to the foredeck stairs.

Below decks is a pair of cabins for additional crew, as well as equipment, pump rooms and storage spaces.

Ratayapibanbancha and Arcarachwaratorn will perform a multitude of functions that fall under the jurisdiction of the Royal Thai Police, including border protection, general and long range patrol duties and transporting dignitaries. To this end, the vessels have been configured to be versatile and fully-featured, including comprehensive communication equipment and office facilities. The interior spaces of the vessel are well fitted out in high-quality, durable materials appropriate for the operation.

The vessels’ engineering system installations reflect careful attention to detail. The application of underwater main engine exhaust outlets ensures very low ambient noise levels throughout the vessels and surrounding environment.

The vessels are powered by twin MAN 12V D2862 main engines, each producing 1213kW and feature Humphree interceptors. The vessels performed very well in sea trials, achieving a loaded speed of 32 knots. They are capable of a maximum speed of 34 knots and a cruise speed range of 1,000 miles.
