Sailboat boom

The boom is a horizontal beam attached to the mast at the base of a mainsail or staysail. The boom keeps the sail taut and controls its angle in relation to the wind, which influences the power and direction of the boat. This spar is designed to be strong yet lightweight, to withstand wind forces while minimizing the weight added to the boat. It is often equipped with devices such as sails and sheets to adjust the tension of the sail and adjust its shape according to sailing conditions. The mechanical forces exerted on the boom are mainly in bending; this is why the boom is often thicker in its center to be more rigid. Horizontal spars used on sailboats to control the position and tension of the main (boom) and stay (gui) sails. This spar is generally attached to the end of the sail by trolleys or sliders, which allows the angle of the sail to be adjusted in relation to the wind. It also allows you to trim and spread the sail to optimize its performance in different wind conditions.
