(r) Replacement cleats, blocks and fittings: Replacements shall be fitted in the same position as the standard fitting, or as close as is structurally possible. A cleat may be replaced with a cleat of any material and, substantially the same size and design. A block may be replaced with a block of the same number of sheaves of similar or greater diameter. Ratchet blocks have no sheave diameter restrictions provided they do not alter the weight distribution of the boat.
