Product Introduction
50m Steel-Aluminum High Speed Patrol Boat Full English Introduction
Vessel Overview
This 50-meter steel-aluminum composite monohull patrol vessel is a mature multi-mission law enforcement craft designed for coastal territorial waters, offshore supervision, anti-smuggling, fishery inspection, maritime security patrol and emergency search & rescue operations. Adopting classic steel hull + lightweight aluminum superstructure hybrid construction, the vessel balances robust structural strength, outstanding corrosion resistance and lightweight performance, effectively reducing overall displacement while improving speed and seakeeping capability in rough coastal seas.
The hull features optimized round-bilge wave-piercing lines fitted with bilge keels and stabilizers to minimize rolling during long-duration patrols. Equipped with a triple-engine triple-propulsion system and twin rudders plus bow thruster, the patrol boat delivers ultra-responsive maneuverability, reliable acceleration and stable high-speed interception performance, well-suited for long-distance continuous offshore missions. The fully enclosed intelligent wheelhouse integrates a complete suite of maritime navigation, communication and electro-optic surveillance systems to support all-weather 24-hour law enforcement monitoring and evidence collection. Spacious crew accommodation, independent galley and rest lounge are arranged to guarantee crew comfort during multi-day offshore self-sustained patrol tasks.

Propulsion & Power System
Three high-power marine diesel main engines matched with customized reduction gearboxes provide abundant thrust for high-speed pursuit and interception. Twin 90kW auxiliary generator sets supply stable power for all navigation equipment, surveillance systems, air conditioning and daily living facilities. The full-flow cooling and noise reduction layout cuts mechanical vibration and cabin noise significantly, improving long-operation comfort.
Navigation, Surveillance & Safety Outfit
The vessel is outfitted with dual-channel marine radar, ECDIS electronic chart system, DGPS & Beidou dual-mode positioning, AIS vessel identification, VSAT satellite communication, GMDSS global distress communication, and high-definition electro-optic tracking camera with remote video transmission for real-time law enforcement evidence recording. Standard full-set lifesaving and fire-fighting appliances including life rafts, life jackets, fire monitors and portable extinguishers are fully equipped to meet international maritime safety standards for coastal official craft.
Main Application Scenarios
- Fishery administration patrol, illegal fishing inspection and marine resource protection;
- Customs anti-smuggling interception, cargo inspection and border water security;
- Maritime law enforcement, water traffic supervision and emergency accident disposal;
- Coastal security patrol, water event security and offshore search & rescue;
- Multi-department joint law enforcement command and offshore inspection missions.
Vessel Advantages
- Steel-aluminum composite structure: Strong anti-corrosion performance, lower weight, lower fuel consumption and longer service life compared to full-steel patrol boats;
- Triple-engine propulsion design: Fast acceleration, flexible turning, powerful interception capacity under full load;
- Excellent seakeeping design: Low rolling motion to reduce crew fatigue during long patrols;
- Complete intelligent monitoring system: Integrated communication, positioning and surveillance to realize digital law enforcement;
- Ample storage, accommodation and working deck space to carry patrol equipment, rescue tools and auxiliary RHIB.
