Regulation 29
Correction to the Freeboard for Ships
under 100 metres (328 feet) in length
The tabular freeboard for a Type "B" ship of between 24 metres
(79 feet) and 100 metres (328 feet) in length having enclosed
superstructures with an effective length of up to 35 per cent of the
length of the ship shall be increased by:
----------------------------------------------------------------------
| E |
| 7.5(100 - L)(0.35 - ---) millimetres |
| L |
----------------------------------------------------------------------
where L = length of ship in metres,
E = effective length of superstructure in metres as defined in
Regulation 35; or
----------------------------------------------------------------------
| E |
| 0.09(328 - L)(0.35 - ---) inches |
| L |
----------------------------------------------------------------------
where L = length of ship in feet,
E = effective length of superstructure in feet as defined in
Regulation 35.
Regulation 30
Correction for Block Coefficient
Where the block coefficient (C ) exceeds 0.68, the tabular
b
freeboard specified in Regulation 28 as modified, if applicable, by
Regulations 27 (8), 27 (10) and 29 shall be multiplied by the factor
----------------------------------------------------------------------
| C + 0.68 |
| b |
| ---------- |
| 1.36 |
----------------------------------------------------------------------
Regulation 31
Correction for Depth
(1) Where D exceeds L/15 the freeboard shall be increased by (D -
L/15) R millimetres, where R is L/0.48 at lengths less than 120 metres
and 250 at 120 metres length and above, or (D - L/15) R inches, where
R is L/131.2 at lengths less than 393.6 feet and 3 at 393.6 feet
length and above.
(2) Where D is less than L/15 no reduction shall be made except
in a ship with an enclosed superstructure covering at least 0.6 L
amidships, with a complete trunk, or combination of detached enclosed
superstructures and trunks which extend all fore and aft, where the
freeboard shall be reduced at the rate prescribed in paragraph (1) of
this Regulation.
(3) Where the height of superstructure or trunk is less than the
standard height, the reduction shall be in the ratio of the actual to
the standard height as defined in Regulation 33.
Regulation 32
Correction for Position of Deck Line
Where the actual depth to the upper edge of the deck line is
greater or less than D, the difference between the depths shall be
added to or deducted from the freeboard.
Regulation 33
Standard Height of Superstructure
The standard height of a superstructure shall be as given in the
following table:
Standard Height (in metres)
-------------------------------------------------------------------
| L | Raised | All other |
| (metres) | Quarter Deck | Superstructures |
|-------------------------|--------------------|------------------|
| 30 or less | 0.90 | 1.80 |
|-------------------------|--------------------|------------------|
| 75 | 1.20 | 1.80 |
|-------------------------|--------------------|------------------|
| 125 or more | 1.80 | 2.30 |
-------------------------------------------------------------------
Standard Height (in feet)
-------------------------------------------------------------------
| L | Raised | All other |
| (feet) | Quarter Deck | Superstructures |
|-------------------------|--------------------|------------------|
| 98.5 or less | 3.0 | 5.9 |
|-------------------------|--------------------|------------------|
| 246 | 3.9 | 5.9 |
|-------------------------|--------------------|------------------|
| 410 or more | 5.9 | 7.5 |
-------------------------------------------------------------------
The standard heights at intermediate lengths of the ship shall be
obtained by linear interpolation.
Regulation 34
Length of Superstructure
(1) Except as provided in paragraph (2) of this Regulation, the
length of a superstructure (S) shall be the mean length of the parts
of the superstructure which lie within the length (L).
(2) Where the end bulkhead of an enclosed superstructure extends
in a fair convex curve beyond its intersection with the superstructure
sides. the length of the superstructure may-be increased. This
increase shall be two-thirds of the fore and aft extent of the portion
of superstructure formed by the curved bulkhead. The maximum curvature
which may be taken into account in determining this increase is
one-half the breadth of the superstructure at the point of
intersection of the curved end of the superstructure with its side.
Regulation 35
Effective Length of Superstructure
(1) Except as provided for in paragraph (2) of this Regulation,
the effective length (E) of an enclosed superstructure of standard
height shall be its length.
(2) In all cases where an enclosed superstructure of standard
height is set in from the sides of the ship as permitted in Regulation
3 (10), the effective length shall be the length modified by the ratio
of b/Bs, where b is the breadth of the superstructure at the middle of
its length; and Bs is the breadth of the ship at the middle of the
length of the superstructure.
Where a superstructure is set in for a part of its length, this
modification shall be applied only to the set in part.
(3) Where the height of an enclosed superstructure is less than
the standard height, the effective length shall be its length reduced
in the ratio of the actual height to the standard height. Where the
height exceeds the standard, no increase shall be made to the
effective length of the superstructure.
(4) The effective length of a raised quarter deck, if fitted with
an intact front bulkhead, shall be its length up to a maximum of 0.6
L. Where the bulkhead is not intact, the raised quarter deck shall be
treated as a poop of less than standard height.
(5) Superstructures which are not enclosed shall have no
effective length.
Regulation 36
Trunks
(1) A trunk or similar structure which does not extend to the
sides of the ship shall be regarded as efficient on the following
conditions:
(a) the trunk is at least as strong as a superstructure;
(b) the hatchways are in the trunk deck, and the hatchway
coamings and covers comply with the requirements of Regulations 13 to
16 inclusive and the width of the trunk deck stringer provides a
satisfactory gangway and sufficient lateral stiffness. However, small
access openings with watertight covers may be permitted in the
freeboard deck;
(c) a permanent working platform fore and aft fitted with guard
rails is provided by the trunk deck, or by detached trunks connected
to superstructures by efficient permanent gangways;
(d) ventilators are protected by the trunk and watertight covers,
if the height of the ventilator is below that specified in Regulation
19 (3) of this Annex;
(e) open rails are fitted on the weather parts of the freeboard
deck in way of the trunk for at least half their length;
(f) the machinery casings are protected by the trunk, by a
superstructure of at least standard height, or by a deckhouse of the
same height and of equivalent strength;
(g) the breadth of the trunk is at least 60 per cent of the
breadth of the ship; and
(h) where there is no superstructure, the length of the trunk is
at least 0.6 L.
(2) The full length of an efficient trunk reduced in the ratio of
its mean breadth to В shall be its effective length.
(3) The standard height of a trunk is the standard height of a
superstructure other than a raised quarter deck.
(4) Where the height of a trunk is less than the standard height,
its effective length shall be reduced in the ratio of the actual to
the standard height. Where the height of hatchway coamings on the
trunk deck is less than that required under Regulation 15 (1), a
reduction from the actual height of trunk shall be made which
corresponds to the difference between the actual and the required
height of coaming.
Regulation 37
Deduction for Superstructures and Trunks
(1) Where the effective length of superstructures and trunks is
1.0 L, the deduction from the freeboard shall be 350 millimetres at 24
metres length of ship, 860 millimetres at 85 metres length, and 1070
millimetres at 122 metres length and above (14 inches at 79 feet
length of ship, 34 inches at 279 feet length, and 42 inches at 400
feet length and above); deductions at intermediate lengths shall be
obtained by linear interpolation.
(2) Where the total effective length of superstructures and
trunks is less than 1.0 L the deduction shall be a percentage obtained
from one of the following tables:

Regulation 38
Sheer
General
(1) The sheer shall be measured from the deck at side to a line
of reference drawn parallel to the keel through the sheer line
amidships.
(2) In ships designed with a rake of keel, the sheer shall be
measured in relation to a reference line drawn parallel to the design
load waterline.
(3) In flush deck ships and in ships with detached
superstructures the sheer shall be measured at the freeboard deck.
(4) In ships with topsides of unusual form in which there is a
step or break in the topsides, the sheer shall be considered in
relation to the equivalent depth amidships.
(5) In ships with a superstructure of standard height which
extends over the whole length of the freeboard deck, the sheer shall
be measured at the superstructure deck. Where the height exceeds the
standard the least difference (Z) between the actual and standard
heights shall be added to each end ordinate. Similarly, the
intermediate ordinates at distances of 1/6 L and 1/3 L from each
perpendicular shall be increased by 0.444 Z and 0.111 Z respectively.
(6) Where the deck of an enclosed superstructure has at least the
same sheer as the exposed freeboard deck, the sheer of the enclosed
portion of the freeboard deck shall not be taken into account.
(7) Where an enclosed poop or forecastle is of standard height
with greater sheer than that of the freeboard deck, or is of more than
standard height, if paragraph (6) of this Regulation has not been used
an addition to the sheer of the freeboard deck shall be made as
provided in paragraph (12) of this Regulation.
Standard Sheer Profile
(8) The ordinates of the standard sheer profile are given in the
following table:

-----------------------------------------------------------------------
Measurement of Variation from Standard Sheer Profile
(9) Where the sheer profile differs from the standard, the four
ordinates of each profile in the forward or after half shall be
multiplied by the appropriate factors given in the table of ordinates.
The difference between the sums of the respective products and those
of the standard divided by 8 measures the deficiency or excess of
sheer in the forward or after half. The arithmetical mean of the
excess or deficiency in the forward and after halves measures the
excess or deficiency of sheer.
(10) Where the after half of the sheer has an excess and the
forward half of the sheer has a deficiency, no credit shall be allowed
for the part in excess and deficiency only shall be measured.
(11) Where there is an excess in the forward half of the sheer
and in the after half there is a deficiency which does not exceed 25
per cent, credit shall be allowed for the excess. When the deficiency
in the after part of the sheer exceeds 50 per cent, then no credit
shall be given for the excess sheer forward. When the deficiency of
the after sneer is between 25 per cent and 50 per cent intermediate
allowances may be granted for excess sheer forward.
(12) When the actual height of a poop or forecastle at the end
ordinate exceeds the standard the following formula shall be used:
----------------------------------------------------------------------
| y L` |
| s = --- --- |
| 3 L |
----------------------------------------------------------------------
where s = sheer credit, to be deducted from the deficiency or
added to the excess of sheer,
y = difference between actual and standard height of
superstructure at the end ordinate in millimetres (inches),
L` = mean enclosed length of poop or forecastle up to a maximum
length of 0.5 L,
L = length of ship as defined in Regulation 3 (1) of this Annex.
The above formula provides a curve in the form of a parabola
tangent to the actual sheer curve at the freeboard deck and
intersecting the end ordinate at a point below the superstructure deck
a distance equal to the standard height of a superstructure. The
superstructure shall not be less than standard height above this curve
at any point. This curve shall be used in determining the sheer
profile for forward and after halves of the ship.
Correction for Variations from Standard Sheer Profile
(13) The correction for sheer shall be the deficiency or excess
of sheer (see paragraphs (9) to (12) inclusive of this Regulation),
multiplied by
----------------------------------------------------------------------
| S |
| 0.75 - ---- |
| 2L |
----------------------------------------------------------------------
where S is the total length of enclosed superstructures.
Addition for Deficiency in Sheer.
(14) Where the sheer is less than the standard, the correction
for deficiency in sheer (see paragraph (13) of this Regulation) shall
be added to the freeboard.
Deduction for Excess Sheer
(15) In ships where an enclosed superstructure covers 0.1 L
before and 0.1 L abaft amidships, the correction for excess of sheer
as calculated under the provisions of paragraph (13) of this
Regulation shall be deducted from the freeboard; in ships where no
enclosed superstructure covers amidships, no deduction shall be made
from the freeboard; where an enclosed superstructure covers less than
0.1 L before and 0.1 L abaft amidships, the deduction shall be
obtained by linear interpolation. The maximum deduction for excess
sheer shall be at the rate of 125 millimetres per 100 metres of length
(1 1/2 inches per 100 feet of length).
Regulation 39
Minimum Bow Height

Regulation Is obtained by sheer, the sheer shall extend for at least
15 per cent of the length of the ship measured from the forward
perpendicular. Where it is obtained by fitting a superstructure, such
superstructure shall extend from the stem to a point at least 0.07 L

(8) When timber is in lengths less than 3.6 metres (11.8 feet)
the spacing of the lashings shall be reduced or other suitable
provisions made to suit the length of timber.
(9) All fittings required for securing the lashings shall be of
strength corresponding to the strength of the lashings.
Stability
(10) Provision shall be made for a safe margin of stability at
all stages of the voyage, regard being given to additions of weight,
such as those due to absorption of water and icing and to losses of

RECOMMENDATIONS
The following are the Recommendations adopted by the Conference:
Recommendation 1
Denunciation of the International Convention
Respecting Load Lines, 1930
The Conference recommends:
(1) that Governments should accept the International Convention
on Load Lines, 1966, at as early a date as possible and that the
Governments which become parties to that Convention should denounce
the International Convention respecting Load Lines, 1930, and should
co-operate with one another with a view to ensuring that their
respective denunciations become effective on a date two years after
the date on which the 1966 Convention comes into force;
(2) that Governments denouncing the 1930 Convention should bear
in mind the provisions of the 1966 Convention relating to existing
ships, in particular Article 4 (4).
Recommendation 2
Ships not Subject to the International
Convention on Load Lines, 1966
The Conference recommends that such regulations as may be made by
any of the Contracting Governments relating to:
(1) its new ships of less than 24 metres (79 feet) in length on
international voyages;
(2) its existing ships of less than 150 tons gross engaged on
international voyages;
(3) its ships engaged on national voyages of an exposed nature,
embracing the same hazardous elements as are normally encountered on
international voyages
should, so far as practicable and reasonable, be framed in
accordance with the principles and provisions of the International
Convention on Load Lines, 1966.
Recommendation 3
Minimum Freeboards for Fishing Vessels
The Conference, having discussed the possibility of assigning
load lines to fishing vessels, recommends that the Inter-Governmental
Maritime Consultative Organization should pursue studies on the
minimum freeboard for such vessels with a view to establishing
recommended international standards for minimum freeboard of fishing
vessels.
Recommendation 4
Consolidation of Conventions
The Conference, recognizing the common aims of the International
Convention for the Safety of Life at Sea, 1960 and the International
Convention on Load Lilies, 1966, concerning the safety of life and
property at sea, recommends that the Inter-Governmental Maritime
Consultative Organization should consider the relationship between the
provisions of the two Conventions with a view to suggesting how they
could be consolidated in a single international convention.
Recommendation 5
Boundaries between Inland Wafers and the Sea
The Conference recommends that each Contracting Government should
make available to any other Contracting Government, on request,
particulars of the boundaries between inland waters and the sea which
it will use for the purposes of Article 12 (3) of the International
Convention on Load Lines, 1966.
