The stabilization fins were designed to improve the ASV's directional control and mitigate lateral forces caused by wind and water interactions. Their frontal design was inspired by configurations commonly used in the market for more complex hulls, which were specifically adapted to our vessel's requirements. Based on drag force calculations, each fin was designed with an area of 23 in².The fins are positioned at the center of hulls, where the highest lateral forces occur due to interactions around the component boxes. Manufactured using 3D printing technology, PLA was chosen as the material for its affordability, accessibility, and suitability for the project’s constraints.

For propulsion, the ASV is equipped with two T200 thrusters, each capable of delivering 10 pounds of thrust. The vessel’s directional configuration is differential, allowing for precise maneuverability by independently controlling the speed and direction of each thruster.

The ASV's frame is constructed from an aluminum alloy, chosen for its lightweight properties, high strength, and excellent resistance to corrosion. This design not only provides durability but also modularity and structural integrity, making the ASV highly adaptable for various applications. To further ensure long-term resistance to corrosion, stainless steel screws are used throughout the structure. Together, these design choices contribute to a lightweight build, resulting in a total vessel weight of 44 lb.
