11.7m - Bangladesh Small Patrol Boat

Two variants of this compact military vessel have been designed for Bangladeshi Navy and Coastguard and a number of each are programmed for construction.


Initial prototypes and tooling were constructed by North Sea Boats in East Java, Indonesia, whilst future boats will be built in Bangladesh under the terms of a technology transfer deal with North Sea boats.


Intended for multiple roles, the boats are currently configured to carry a number of troops, but can equally be set up to transport equipment, operate routine patrols in harbours, estuaries and delta, or perform intercept and apprehension duties etc.


The boats are built using resin infused medium tech E-glass foam sandwich from female tools. 


Powering for the first production run is via twin Volvo D6 diesels turning conventional propellers in tunnels for reduced draft. 


Performance is strong - the propellers offering excellent acceleration and a sprint speed of close to 40 knots.  Maneuverability at speed is also surprisingly good and sea trials in 2m+ seas raised by overfalls in the Bali Strait proved the hull to be soft riding and sea kindly.


This design should find application in a wide variety of military, Government Authority and security roles and with relatively minor modifications could be readily adapted to more specific tasks - the introduction of water jets and bow doors for instance could see the boat operating as a combat boat capable of beach landings.
