In ships without rudder stock (e.g. ships fitted with azimuth thrusters), the Rule length $L$ is to be taken equal to 97% of the extreme length on the waterline at the scantling draught. In ships with unusual stern and bow arrangement the Rule length $L$ will be specially considered.(ref. IACS S2 Definition of Ship's Length $L$ and of Block Coefficient $C_b$ - S2.1 Rule Lenght). | | [[ocx-if:draft-schema:ocx:ScantlingDraught|ScantlingDraught]] | ocx | ocx:Quantity_T | req. | [1, 1] | False | Design draught moulded, fully loaded condition, Td.
