Boat Hull Design For Speed
However, hull design isn’t just about speed and interior volume. there’s also stability and tenderness, which is a boat’s tendency to rock. the boats described above have planing hulls, which means they have hard chines.. How much the hull surface contacts the water directly determines the amount of drag a hull suffers. steps (also called vents) decrease the amount of hull contacting the water (called the wetted surface), thereby decreasing drag, increasing speed for the same horsepower, and increasing fuel efficiency. it all sounds good..
