Boat design involves creating the shape and structure of a boat to ensure it is functional, safe, and efficient on water. Designers consider factors like the boat's purpose, size, and materials. Common types of boats include sailboats, motorboats, and fishing boats, each requiring different design elements to perform well in their specific environments. Key aspects of boat design include hydrodynamics, which affects how the boat moves through water, and stability, which ensures it remains upright. Designers also focus on aesthetics and comfort, incorporating features like seating, storage, and navigation systems to enhance the user experience.
