The mid-transverse section is considered one of the significant sections in the shiphull, because it exists in the middle of its calculated length, where the bindings moments reach the maximum, in consequence the hull strength can be determined through the strength of this section. Its design process includes the determination of the dimensions of plats and different framing beams and considered one of the important stages in the hull design process. This research includes the estimation of calculated values of binding moments, inertia and resistant’s moments of this section area, initiated from the providing conditions of critical strength and fatigue strength. It also includes, the formals used for the determination of longitudinal elements dimensions through the transverse thicknesses and metal distribution type among them. The longitudinal strength of the hull was evaluated according the perpendicular and tangential stresses.
