Rescue boats are divided into general speed rescue boats (>6 knots/6 passengers) and high-speed rescue boats (>20 knots/up to 16 passengers)
The engine is divided into a outboard engine (gasoline engine) and an inboard diesel engine, equipped with a propulsion device. Generally, rescue boats are equipped with propellers, and high-speed rescue boats are equipped with water jet thrusters
The work boat can serve as a liaison communication, personnel transportation, maintenance, channel measurement, supply of supplies, etc.
According to the number of passengers and speed requirements, the rescue boat model and technical parameters are shown in the table below:
