The weight classification system presented in this volume is a revision of the Maritime Commission system published under a similar title in July 1940. This system is now in general use among merchant ship designers and builders in the United States. No basic changes have been made in the classification system but descriptions have been clarified and enlarged to include new equipment and materials now common in the industry. The copious, cross-referenced index has been expanded to include these new items and now generally encompasses by common name every item of equipment and material found on a modern merchant vessel. The system comprises three major groupings: Steel-Groups 0-0 to 9-9, Outfit-Groups 10-0 to 19-9, Machinery-Groups 20-0 to 29-9, The major groupings encompass all of the light ship weight which is further defined as follows: The light ship weight shall be the weight of the ship with all its equipment and outfit, including permanent ballast (solid and liquid), spare parts, regardless of by whom furnished, water in boilers to normal steaming level, machinery in working condition, lubricating oil in all machinery, but not in storage tanks, water in piping systems in the machinery spaces, water in fresh water systems and firemains, but without any items of consumable or variable load, as liquids in double bottom tanks, deep tanks, storage or reserve supply tanks or any allowance for cargo, stores, passengers, crew and their effects.
