entitled to fly, the validity of the certificate may be extended by thatParty, but such extension shall be granted only for the purpose of
allowing the vessel to complete its voyage to a port of that Party or tothe port in which it is to be surveyed and then only in cases where it
appears proper and reasonable to do so.
(3) No certificate shall be thus extended for a period longer than
five months and a vessel to which such extension is granted shall not onits arrival in a port of the Party whose flag the vessel is entitled to

|-----| heel of 30
degrees and 40 degrees or between 30 degrees andθ(f), if this angle is
less than 40 degrees shall not be less than 0.030 metre-radians.θ(f) isthe angle of heel at which openings

the stability parameters contained in these criteria. The Administrationshall also be satisfied that those special conditions associated with a
change in the vessel''s mode or areas of operation which affect the
stability considerations of this Chapter are taken into account.
(3) Concerning the conditions referred to in paragraph (1), the
calculations shall include the following:
(a) allowance for the weight of the wet fishing nets and tackle,
etc. on the deck;
(b) allowance for ice accretion, if anticipated, in accordance
with the provisions of Regulation 34;

and the actual displacement and position of the centre of gravity shall be
determined for the light ship condition.
(2) Where alterations are made to a vessel affecting its light ship
condition and the position of the centre of gravity, the vessel shall, if
the Administration considers this necessary, be re-inclined and the
stability information revised.
(3) The Administration may allow the inclining test of an individual
vessel to be dispensed with provided basic stability data are available
from the inclining test of a sister ship and it is shown to the
satisfaction of the Administration that reliable stability information for
the exempted vessel can be obtained from such basic data.

accessible at all times and inspected at the periodical surveys of the
vessel to ensure that it has been approved for the actual operating
conditions.
(3) Where alterations are made to a vessel affecting its stability,
revised stability calculations shall be prepared and submitted to the
Administration for approval. If the Administration decides that the
stability information must be revised, the new information shall be
supplied to the skipper and the superseded information removed.

Administration, to prevent the excessive shipping of water and shall be
determined taking account of the seasonal weather conditions, the sea
states in which the vessel will operate, the type of vessel and its mode
of operation.****
[**** See Guidance on a Method of Calculation of Bow Height contained
in Recommendation 5 of Attachment 3 to the Final Act of the Conference.]
Regulation 39 Maximum Permissible Operating Draught
A maximum permissible operating draught shall be approved by the
