Summary (AI generated)

In my journey into aerospace, I developed a strong interest in aircraft dynamics. I experienced firsthand how aerodynamic forces impact performance. For instance, when a wing is sufficiently strong, wave drag can be significantly reduced, allowing for increased speed. However, challenges such as separation can arise, which complicates the dynamics.

Now, let's examine a conventional sailboat. Consider the innovative project from Chalma's University, which involved lifting an optimist sailboat—a design intended for children and known for its slow speed—out of the water by utilizing an underwater wing. This project successfully demonstrated the concept.
