Fast boats are the 'sprinters' among naval vessels, with top speeds reaching 40-60 knots, earning them the nickname of 'marine light cavalry.' Fast boats are classified by their weaponry, including torpedo boats, missile boats, and missile torpedo boats. Although small, fast boats pack a punch, with significant roles. For large or medium-sized enemy warships that have intruded into the near-shore range, torpedo boats and missile boats can engage independently or in coordination with other surface vessels to destroy the intruding enemy ships. They can also be dispatched to attack enemy convoys, disrupting enemy maritime transportation lines. Fast boats are fast, with small hulls that can be stealthy and effectively launch surprise attacks on enemy bases and anchorage areas. In shallow channels, narrow seas, and areas with reefs and islands, 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 with large and medium-sized vessels, they have weaker self-defense capabilities and poor performance in withstanding storms and waves, making them suitable for operations in close-to-shore waters.

Modern high-speed 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, high-speed 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.
