BS EN ISO 8666 The lengths of a craft shall be measured parallel to the maximum load waterline/reference waterline and craft centreline as the distance between two vertical planes, perpendicular to the centreplane of the craft. 5.2.2 Maximum length, Lmax The maximum length (Lmax) shall be measured in accordance with 5.2.1, one plane tangent through the foremost part and the other through the aftermost part of the craft. This length includes all structural and integral parts of the craft, such as stems or sterns, bulwarks, and hull/deck joints. This length includes parts which are normally fixed, such as fixed spars, bowsprits, pulpits at either end of the craft, stemhead fittings, rudders, outboard motor brackets, outdrives, waterjets, and any propulsion units extending beyond the transom, diving and boarding platforms, rubbing strakes, and permanent fenders.Outdrives, waterjets, other propulsion units, and all movable parts shall be measured in their normal operating condition to their maximum lengthwise extension when the craft is underway. This length excludes the following: – outboard motors; 一any other type of equipment that can be detached without the use of tools.See Figure 1 for monohull measurements and Figure 2 for multihull measurements.The length of the hull (LH) shall be measured in accordance with 5.2.1, one plane passing through the foremost part of the craft and the other through the aftermost part of the craft. This length includes all structural and integral parts of the craft, such as stems or sterns, bulwarks, and hull/deck joints. This length excludes removable parts that can be detached in a non-destructive manner and without affecting the structural integrity of the craft, e.g. spars, bowsprits, pulpits at either end of the craft, stemhead fittings, rudders, outdrives, outboard motors and their mounting brackets and plates, diving platforms, boarding platforms, rubbing strakes, and fenders if they do not act as hydrostatic support when the watercraft is at rest or underway.With multihull craft, the length of each hull shall be measured individually. The length of the hull, LH,shall be taken as the longest of the individual measurements.See Figure 1 for monohull measurements and Figure 2 for multihull measurements.BS EN ISO 8666 pdf download.
