A fast boat is the 'sprint' of warships, with a maximum speed of 40-60 knots, known as the 'marine light cavalry'. Fast boats are classified by the equipment of weapons, including torpedo boats, missile boats, and missile torpedo boats. Although small, a fast boat has considerable power and plays a significant role. For large or medium-sized enemy warships that have intruded into the near sea, torpedo boats and missile boats can attack individually or in coordination with other surface vessels to destroy the intruding enemy ships. They can also send fast boats to attack enemy convoys and destroy enemy sea transportation lines. Fast boats are fast, small in size, and can be concealed, effectively carrying out sudden attacks on enemy bases and anchorage areas. In shallow channels, narrow seas, reef and island areas, fast boats can be used for mine laying.

Among the fast boats, the most powerful are missile boats, which inherit the advantages of torpedo boats and play a very important role in naval battles. However, compared to large and medium-sized vessels, they have weaker self-defense capabilities and poor performance in weather resistance, making them suitable only for operations in close-to-shore waters.

Modern fast boats are widely applied with missile weapons, advanced miniaturized electronic equipment, large-power gas turbines, and water wings and air cushion technology, and are developing towards the directions of missileization, large-scale, high-speed, and electrification. In future naval battles, fast boats will play a greater role.

Science Project:

1. Prepare the necessary materials for the experiment, including EVA, a pipette, a battery box, a motor, and fan blades, etc....
Step 2: Install according to the instructions in the manual.
3, Install and debugging.

Science Expansion:
Fast boats have small tonnage, high speed, and are highly maneuverable. Their displacement is usually in the tens to hundreds of tons, with a cruising speed of 30 to 40 knots, and some can reach up to 50 knots. Their endurance is 500 to 3,000 nautical miles. Fast boats are equipped with weapons, and some are also fitted with 20 to 76 mm caliber naval guns. Larger tonnage fast boats may also include mines, depth charges, and other weapons. The sensing systems they are equipped with include search, detection, weapon control, communication navigation, and electronic warfare.
