3. This Part applies to ships, being ships of 24 metres in length or over, registered or to be registered in the United Kingdom under Part II of the Act and for which the ascertainment of tonnage is required under Regulations made under section 10 of the Act.
4.-(1) A ship shall be measured by a surveyor.
(2) The gross and net tonnages shall be determined in accordance with regulations 6 and 7 provided that in the case of novel types of craft with constructional features which render the application of the provisions of these Regulations unreasonable or impracticable, the gross and net tonnages shall be determined as required by the Secretary of State.
(3) All measurements used in the calculations of volumes shall be taken and expressed in metres to the nearest one hundredth of a metre.
(4) Gross and net tonnages shall be expressed as whole numbers, decimals being rounded off downwards.
5.-(1) All volumes included in the calculation of gross and net tonnages shall be measured, irrespective of the fitting of insulation or the like, to the inner side of the shell or structural boundary plating in ships constructed of metal, and to the outer surface of the shell or to the inner side of the structural boundary surfaces in ships constructed of any other material.
(2) Volumes of appendages shall be included in the total volume.
(3) Volumes of spaces open to the sea shall be excluded from the total volume.
(4) The method and accuracy of the calculations shall be sufficiently detailed to facilitate checking.
6. The gross tonnage (GT) of a ship shall be determined by the following formula-
GT = K1V
where-
V = total volume of all enclosed spaces of the ship in cubic metres; and
K1 = 0.2 + 0.02 log10 V, as specified in Schedule 2;
7. The net tonnage (NT) of a ship shall be determined by the following formula-

N1 and N2 shall be taken as zero when N1 + N2 is less than 13; and
NT shall not be taken as less than 0.30 GT.
8. Where segregated ballast tanks complying with Regulation 13 of Annex 1 of the International Convention for the Prevention of Pollution from Ships 1973(8), as modified by the Protocol of 1978(9) relating to that Convention, are provided in oil tankers, an entry may be made on the International Tonnage Certificate (1969) indicating the total tonnage of these tanks. The tonnage of such segregated ballast shall be calculated according to the following formula-
K1 × Vb
where-
K1 = 0.2 + 0.02 log10 V, as specified in Schedule 2;
V = the total volume of all enclosed spaces of the ship in cubic metres; and
Vb = the total volume of segregated ballast tanks in cubic metres measured in accordance with regulation 5.
9. If it is in order to do so, the Certifying Authority shall issue to the owner an International Tonnage Certificate (1969) in the form set out in the Convention certifying the tonnages of the ship and containing the particulars to be shown thereon. The official number of the ship shall be included as a distinctive number.
10.-(1) Where alterations are made in the arrangement, construction, capacity, use of spaces, total number of passengers the ship is permitted to carry under the terms of the ship's passenger certificate, assigned load line, or permitted draught of the ship such as would cause an increase in the gross or net tonnage, the existing International Tonnage Certificate (1969) shall cease to be valid and shall be delivered up to and cancelled by the Certifying Authority.
(2) When a ship is transferred from the United Kingdom Register the International Tonnage Certificate (1969) shall cease to be valid except when the transfer is to the Administration of a state which is a Contracting Government, in which case the certificate may remain in force for a period not exceeding 3 months or until the new Administration issues another International Tonnage Certificate (1969), whichever is the earlier. The Certifying Authority shall transmit to the Administration of that Government as soon as possible after the transfer has taken place a copy of the certificate carried by the ship at the time of transfer and a copy of the relevant tonnage calculations.
11.-(1) When alterations in the values of V, Vc, d, N1 or N2 as defined in regulations 6 and 7 result in an increase in the net tonnage a new International Tonnage Certificate (1969) incorporating the increased net tonnage shall be issued.
(2) In the case of a passenger ship assigned subdivision load lines in accordance with the Merchant Shipping (Passenger Ship Construction) Regulations 1980 or the Merchant Shipping (Passenger Ship Construction) Regulations 1984 and load lines in accordance with the Load Line Rules only one net tonnage shall be applied. Where the draught corresponding to the Summer load line differs from that corresponding to the deepest subdivision load line the net tonnage shall, subject to paragraph (3)(a), be that determined in accordance with regulation 7 by applying the draught corresponding to the appropriate assigned load line for the trade in which the ship is engaged.
(3) (a) Subject to subparagraph (b) below, where alterations in the values of V, Vc, d, N1 or N2, as defined in regulations 6 and 7, or changes in the position of the load lines result in a decrease in the net tonnage, a new International Tonnage Certificate (1969) incorporating the decreased net tonnage shall not be issued until 12 months have elapsed from the date on which the current certificate was issued.
(b)A new International Tonnage Certificate (1969) may be issued forthwith when-
(i)a ship which was registered outside the United Kingdom is re-registered in the United Kingdom;
(ii)a ship undergoes alterations or modifications of a major character such as the removal of a superstructure, which requires an alteration of the assigned load line; or
(iii)the ship is a passenger ship employed in special trades for carriage of large numbers of special trade passengers, such as the pilgrim trade.
12.-(1) In the case of a ship-
(a)which is a ship the keel of which was laid or which was at a similar stage of construction before 18th July 1982; or
(b)which is a ship the keel of which was laid or which was at a similar stage of construction not later than 31st December 1985, not being a ship referred to in subparagraph (a); or
(c)which is a cargo ship of less than 1600 tons gross tonnage when ascertained in accordance with the provisions of Schedule 5 and Appendices 1 to 4 thereto of the Merchant Shipping (Tonnage) Regulations 1982, the keel of which was laid or which was at a similar stage of construction before 18th July 1994, not being a ship referred to in subparagraph (a);
the Secretary of State may permit the continuing use of a gross tonnage additionally ascertained in accordance with the provisions of Schedule 5 and Appendices 1 to 4 thereto of the Merchant Shipping (Tonnage) Regulations 1982 for the purpose of the application of the provisions of regulations implementing the International Convention for the Safety of Life at Sea 1974(10), the Protocol of 1978 relating to that Convention(11), the International Convention for the Prevention of Pollution from Ships, 1973, the Protocol of 1978 relating to that Convention and the International Convention on Standards of Training, Certification and Watchkeeping of Seafarers, 1978(12), as amended on 7th July 1995.
(2) An International Tonnage Certificate (1969) may be annotated, under "Remarks", by the Certifying Authority-
(a)in the case of ship to which paragraph (1)(a) refers, with the duly completed and signed entry-
"The ship is remeasured according to article 3(2)(d) of the 1969 Tonnage Convention.
The GROSS TONNAGE according to the measurement system previously in force to the measurement system of the International Convention on Tonnage Measurement of Ships, 1969, is: ... ... ... ... RT, according to the regulations ... ... ... ..."; and
(b)in the case of a ship to which paragraph (1)(b) or (c) refers, with the duly completed and signed entry-
"The ship is additionally measured according to resolution A. 494(XII).
The GROSS TONNAGE according to the measurement system previously in force to the measurement system of the International Convention on Tonnage Measurement of Ships, 1969, is: ... ... ... ... RT, according to the regulations ... ... ... ...".
(3) Where such an entry has been made on an International Tonnage Certificate (1969) and the ship undergoes alterations or modifications which affect its tonnage the old tonnage referred to in paragraph (1) shall be deleted.
(4) Where a gross tonnage has been ascertained and is to be used in accordance with paragraph (1), then any certificate issued for the purposes of the conventions and protocols referred to shall record only that gross tonnage together with an appropriate footnote-
"The above gross tonnage has been determined by a Certifying Authority (a tonnage authority) of the United Kingdom in accordance with the national tonnage rules which were in force prior to the coming into force of the International Convention on Tonnage Measurement of Ships, 1969."; or
"See REMARKS column of the valid International Tonnage Certificate (1969)".
13.-(1) This Part shall apply to ships, being ships of less than 24 metres in length, and not being fishing vessels, registered or to be registered under Part II of the Act and for which the ascertainment of tonnage is required under Regulations made under section 10 of the Act.
14.-(1) A ship shall be measured by a surveyor or by a measurer appointed by an organisation authorised by the Secretary of State.
(2) The tonnage of a ship shall be the sum of -
(a)the product of multiplying together its length overall, extreme breadth over the outside hull and depth in metres and multiplying the resultant figure by 0.16; and
(b)the tonnage of any break or breaks, calculated for each break by multiplying together its mean length, mean breadth and mean height in metres and multiplying the resultant figure by 0.35.
(3) For the purpose of this Part-
(a)the breadth of a ship shall be its extreme breadth over the outside plating, planking or hull, no account being taken of rubbers or fenders even if they are moulded so as to be integral with the hull;
(b)the depth of a ship shall be measured vertically at the midpoint of the length overall.
(i)The upper terminal point for depth shall be-
(aa)in the case of a decked ship, the underside of the deck on the middle line or, if there is no deck on the middle line at the point of measurement, the underside of the deck at the side of the ship plus the full deck camber;
(bb)in the case of an open ship, the top of the upper strake or gunwale.
(ii)The lower terminal point of depth shall be-
(aa)in the case of a wooden ship, the upper side of the plank at the side of the keel or hog;
(bb)in the case of a metal ship, the top of the plating at the side of the keel;
(cc)in the case of a glass reinforced plastic ship, the inside of the hull. Where no keel member is fitted and the keel is of open trough construction, the lower terminal point for depth shall be the top of the keel filling, if fitted, or the level at which the inside breadth of the trough is 10 centimetres, whichever gives the greater depth.
(iii)Where a break exists in way of the point of measurement for depth, the height of the break shall not be included in the measurement of depth.
(4) The tonnage determined in accordance with paragraph (2) shall be the gross tonnage and net tonnage.
(5) In the case of a multi-hull ship the tonnage of each hull shall be measured separately and the sum of such tonnages shall be used in computing the tonnage referred to in paragraph (2).
(6) All measurements used in the calculations of volumes shall be taken and expressed in metres to the nearest one hundredth of a metre.
(7) Tonnage shall be expressed to two decimal places, the second decimal place being increased by one if the third decimal place is 5 or more.
(8) On completion of the measurement the surveyor or measurer, as the case may be, shall forward to the Secretary of State a Certificate of Measurement in a form approved by the Secretary of State.
(9) Where alterations are made in the arrangement, construction, capacity, use of spaces, total number of passengers the ship is permitted to carry under the terms of the ship's passenger certificate, assigned load line, or permitted draught of the ship such as would cause an increase in the tonnage, the existing measurement shall cease to be valid, any certificate shall be delivered up to and cancelled by the issuer and the owner of the ship shall make an application for it to be remeasured in accordance with paragraph (1).
(10) Notwithstanding paragraph (2) nothing in this Part shall be taken to require any ship the tonnage of which was validly determined under the law in force immediately before the coming into force of these Regulations to have its tonnage re-determined.
15.-(1) The Secretary of State may , at the request of the Administration of a Contracting Government, ascertain the gross and net tonnages of a non-United Kingdom ship in accordance with Part II and issue to the owner an International Tonnage Certificate (1969). In such cases the certificate shall be endorsed to the effect that it has been issued at the request of the Government of the state whose flag the ship is or will be flying, and a copy of the certificate and the calculations of the tonnages shall be transmitted to the requesting Government as soon as possible.
(2) The Certifying Authority may, at the request of an owner of a non-United Kingdom ship flying the flag of a State whose Government is not a Contracting Government, ascertain the gross and net tonnages of the ship in accordance with Part II and issue a Certificate of British Tonnage measurement. In such a case the certificate shall bear the endorsement "for use only whilst within United Kingdom waters".
16. Any owner or master who fails without reasonable cause to deliver up a certificate for cancellation as required by regulations 10(1) or 14(9) shall be guilty of an offence punishable on summary conviction by a fine not exceeding level 3 on the standard scale.

(This note is not part of the Regulations)
These Regulations consolidate with amendments the Merchant Shipping (Tonnage) Regulations 1982, as amended.
The Regulations re-enact those provisions of the earlier Regulations relating to the International Convention on Tonnage Measurement of Ships 1969 (Cmnd. 4332) (Part II), and the calculation of tonnage for pleasure vessels of less than 13.7 metres in length (Part III).
The Regulations simplify the earlier tonnage requirements for ships of less than 24 metres in length by adopting a method of tonnage computation, previously restricted to those pleasure vessels of less than 13.7 metres in length, for all ships under 24 metres in length other than fishing vessels.
The Regulations deal with the tonnage computation of segregated ballast oil tankers, and with the use of gross tonnage which has been ascertained under previous Regulations.
The Regulations enable the Secretary of State to authorise persons to act as Certifying Authorities for the purpose of the Regulations. Currently so authorised are Lloyd's Register of Shipping, the British Committee of Bureau Veritas, the British Committee of Det Norske Veritas, the British Committee of Germanischer Lloyd: the British Committee of Registro Italiano Navale and the British Technical Committee of the American Bureau of Shipping.
The Conventions and Protocols referred to in the Regulations may be obtained from the International Maritime Organisation, 4 Albert Embankment, London SE1 75R.
