The "nodding donkey" motion of sailboats, where the bow pitches up and down, is not just due to waves. It's amplified by sail trim and hull design. Modern hulls often have a "bulb keel," a large bulb of lead on the keel's bottom to lower the center of gravity, stabilizing this motion. This allows for a slimmer hull, enhancing speed and agility. Fascinatingly, the physics of sailing combines age-old practices with cutting-edge materials and hydrodynamics, creating a dance with the wind and waves. Do you have an interesting fact about boats?
