The Author first discusses the determination of the section modulus and weight distribution of a hull, and examines the loads imposed on the hull structure, keel and bilge blocks, and dock floor while an unladen ship is being lowered on to the blocks during dry-docking, and while it is on the blocks. The characteristics of the blocking arrangement are then discussed, and a proposed design for an "elastic" block is described. The block has rectangular-section cappings of butyl rubber, and a steel body consisting of three pieces, one above another; the intermediate piece, which like the top piece is wedge-shaped, serves for adjusting the height of the block. Hydraulic jacks, which allow quick dismantling of the block to enable hull repairs to be carried out, are incorporated in the block.
