Reg.No

Each record in the register is given a unique number; i.e., the register number. This is for the purposes of identification where there is more than one vessel with a given name. The Reg.No. field is assigned consecutively to the Name in Register, starting from A and finishing at Z.

Return to Top of Page

Off.No

The Off.No field refers to the vessel’s official number, assigned by the flag state where it is registered. Whether or not a vessel was assigned an official number depends upon the flag of registry and its period of service. The UK appears to have been first to adopt a system of official numbers. Other countries followed, but even in the 1930’s Norwegian ships appear not to have an official number.

Vessels having a UK official number are not given any prefix in this listing. However, the official numbers of other nations are distinguished by placing a prefix before the official number. Thus the prefix "s"=Sweden, "g"=Germany, "f"=France, "i"=Italy, "peru"=Peru, "u"=USA, "r"=Russia, "n"=Netherlands, "j"=Japan, "fin"=Finland, "c"=Chile, "p"=Poland.

The official number of a vessel normally remains the same over the entire life of a vessel under a given flag. The exception appears to be Italy where the official number appears to be determined by the port of registry. Thus, a vessel changing its port of registry to another port in Italy was assigned a new official number.

Not all flag states issued an official number. Where a vessel transferred to another flag, it was issued with a new official number for that jurisdiction, at least in jurisdictions that issued an official number. These latter official numbers are listed in the "Notes" field.

Gross

The gross tonnage listed is usually the first value of gross tonnage that appears in the register. The gross tonnage is a volumetric measurement. The vessel may subsequently be remeasured for gross tonnage due to alterations, changes in flag or changes in the gross tonnage rules. Subsequent values of gross tonnage are listed in the "Notes" field using the abbreviation "g" after the numerical value.

Return to Top of Page

Udeck

The Udeck field is the underdeck tonnage; ie, the tonnage beneath the deck. The underdeck tonnage is a volumetric measurement. The vessel may subsequently be remeasured for underdeck tonnage due to alterations or changes in flag. Subsequent values of underdeck tonnage are listed in the "Notes" field using the abbreviation "ud" after the numerical value.

Return to Top of Page

Net

The net tonnage listed is a volumetric measure of the earning capacity of the vessel. The value shown in the net tonnage field is usually the earliest known value unless no gross tonnage was specified at the same time. In the latter case, it is that value at which gross tonnage is also known, and the earliest value is listed in the "Notes" field using the terminology "in" rather than "by".

The vessel may subsequently be remeasured for underdeck tonnage due to alterations, changes in flag or changes in the net tonnage rules. Subsequent values of net tonnage are listed in the "Notes" field using the abbreviation "n" after the numerical value.

Return to Top of Page

Reg. Dimensions

These are the registered length x registered breadth x registered depth in feet. The registered length is usually slightly more that the length between perpendiculars but slightly less than the length of deck. The registered depth is the depth from the deck at side to the top of the ceiling in the hold. In some instances, the registered dimensions change over the life of the vessel. This can be due to alterations such as lengthening, or remeasurement under a new flag State or modified rules for registered dimensions. Where a vessel has subsequent values for registered dimensions, these are recorded in the "Notes" field.

Return to Top of Page

Moulded Depth

The moulded depth is the depth of the vessel in feet and inches from the top of keel to the deck at side. The moulded depth is normally greater than the registered depth in that it includes the depth of floor and ceiling thickness. In some instances, the moulded depth changes over the life of the vessel. This can be due to alterations, or remeasurement under a new flag State or modified rules for measurement of moulded depth. Where a vessel has subsequent values for moulded depth, these are recorded in the "Notes" field using the abbreviation "Mdepth".

Return to Top of Page

Freeboard

The freeboard refers to the summer freeboard from the top of deck at side to the loaded waterline in feet and inches assigned to the vessel. Prior to 1893? the marking of a loadline was not mandatory. Prior to that year, some vessels were marked with the note "freeboard discontinued by owner", apparently at the owner’s discretion. The required freeboard sometimes altered during the life of a vessel. This may be due to modifications to the vessel such as lengthening or the addition of a midship bridge deck; but much more frequently it was due to changes in the requirements specified for the calculation of the minimum freeboard. Where subsequent freeboards are assigned, these have been recorded in the "Notes" field using the abbreviation "FB".

Return to Top of Page

Fate

This field records the eventual fate of the vessel if known including relevant dates. Where the fate has not yet been determined, clues to the fate are recorded such as "Not in L46" which means not in Lloyd’s Register 1946-47. The abbreviation "B/U" refers to the vessel having been broken up. Sometimes additional information concerning the fate is given in the "Notes" field.

Rig Changes and Rig Codes

The rig changes and rig codes field provides information regarding the configuration and alterations to the vessel’s rig. A system of coding has been devised to assist in the identification of individual vessels. Details of the codes are contained in web pages for bowsprits, yards and fore and aft sails attached.

The length after the deck erection code denotes the length of the deck erection in feet. If the notation is in brackets without a question mark, it means that there is evidence that the deck erection was added later in the vessel’s career. If the notation is in brackets with a question mark, that means that there is uncertainty as to whether the notation is correct.

Bulkheads, Ballast, Keel, Donkey Boilers, etc

This field contains technical information such as the following:-

Number of watertight bulkheads. Where the word "bhds" appears without a number in front, then nil bulkheads were fitted or no information has been so far found on the number of bulkheads. The number of bulkheads sometimes varied over a vessel’s career. Information on subsequent changes to the number of bulkheads is provided in the Notes field.

Information as to water ballasting denoted by WB. The following abbreviations apply: db=double bottom, DT=Deep tank, APT=aft peak tank, MT=midship tank, FPT=forepeak tank, t=tons.

Information on the keel depth. For example 12"=Bar keel of depth 12". FK=Flat-plate keel.

Information on donkey boilers if known. db04 means donkey boiler fitted 1904. ndb04 means new donkey boiler 1904 (usually a replacement); Port. means portable.

Information on the nature of fastenings, sheathing and years assigned on composite ships. YM=yellow metal, CS=copper sheathed, CF=copper fastened, GIB=Galvanized iron bolts, As12yrs means assigned 12 years. Some older iron ships were also assigned years and where known, these are given. Note that the years assigned to composite ships changed as more experience was gained on the characteristics of these vessels. Thus the period of years assigned often increased with age. Composite construction was originally considered experimental and many were surveyed biennially.

Information on permanent ballast. Sometimes the field was not large enough to contain all such information in which case the excess information was put into the "Notes" field.
