The invention relates to a rigid boat ball. The rigid boat ball is characterized in that a ball notch through which an earth-rock material can be poured in and out is formed in the upper half ball of a rigid hollow ball, so that an open ball cabin is formed; at least two transverse and six longitudinal stiffeners are arranged on the lower half ball of the rigid hollow ball, and thus the rigid hollow ball has the light upper part and the heavy lower part; the top surface of the earth-rock material poured in the rigid hollow ball is lower than the plane of the ball notch, and thus the rigid hollow ball can drift in a manner of floating on the water. The rigid boat ball has the advantages of low cost in carriage of the earth-rock material, low energy consumption, safety and environmental protection, easy manufacturing, scratch resistance of the rigid material, smooth operation, capability of preventing stormy waves, convenient dragging, tilting and loading and unloading of the earth-rock material, convenient transportation and reuse, capability of preventing water waves or rainwater from entering the cabin, and the like, is suitable for being applied to transporting goods in riverways having falls or in ebb and flow of oceans, and is particularly suitable for being applied to earth rock transportation for canalization.
