The invention provides a sail and navigation equipment. The sail comprises a support rod, a plurality of support skeletons sleeving the support rod in parallel at intervals and a sail body sleeving the support rod and wrapping the plurality of support skeletons, whereinthe section of the sail body in the plane direction perpendicular to the central axis of the support rod is a wing-shaped section;the sail body is provided with a top face allowing one end of the supportrod to extend out and a bottom face allowing the other end of the support rod to extend out, the top face is parallel to the bottom face, and the width of the sail body is gradually increased from the top face to the bottom face. The orthographic projection of the sail body is trapezoidal, the resultant force bearing point of the sail can be effectively reduced, then the external force moment of the support rod is reduced, the structural strength of the support rod is improved, and the sail is prevented from being brokendue to too large impact force of sea waves or sea wind; the section of the sail body in the radial direction of the support rod is designed to be the wing-shaped section, the stress reasonability ofthe sail can be improved, the resistance of navigation equipment is reduced, and the situation that the support rod is broken due to the fact that the sail body is excessively stressed is avoided.

    本申请提供了一种船帆及航行设备,该船帆包括支撑杆、平行间隔套设于支撑杆上的多个支撑骨架和套设于支撑杆上并包裹多个支撑骨架的帆本体,帆本体在垂直于支撑杆之中轴线的平面方向上的截面为翼型截面;帆本体具有供支撑杆的一端伸出的顶面和供支撑杆的另一端伸出的底面,顶面平行于底面,帆本体的宽度由顶面朝向底面的方向逐渐增大。本申请提供的帆本体的正投影为梯形,可有效降低船帆的合力受力点,进而降低支撑杆的外力力矩,进而提高支撑杆的结构强度,避免因海浪或海风的冲击力过大而折断;通过将帆本体沿支撑杆之径向方向的截面设计为翼型截面,可提高船帆受力的合理性,减小航行设备的阻力,避免帆本体受力过大而导致支撑杆的折断。
