(1) The lines which indicate the load line assigned
in accordance with these regulations shall be horizontal lines 230
mm in length and 25 mm in breadth which extend forward of, unless
expressly provided otherwise, and at right angles to, a vertical line
25 mm in breadth marked at a distance 540 mm forward of the centre
of the ring (as illustrated in figure 6.1).
(2) The following load lines shall be used:
-
(a) The Summer Load Line indicated by the upper
edge of the line which passes through the centre of the ring and also
by a line marked S.
-
(b) The Winter Load Line indicated by the upper
edge of a line marked W.
-
(c) The Winter North Atlantic Load Line indicated
by the upper edge of a line marked WNA.
-
(d) The Tropical Load Line indicated by the upper
edge of a line marked T.
-
(e) The Fresh Water Load Line in summer indicated
by the upper edge of a line marked F. The Fresh Water Load Line in
summer is marked abaft the vertical line. The difference between the
Fresh Water Load Line in summer and the Summer Load Line is the allowance
to be made for loading in fresh water at the other load lines.
-
(f) The Tropical Fresh Water Load Line indicated
by the upper edge of a line marked TF and marked abaft the vertical
line.
(3) If timber freeboards are assigned in accordance
with these regulations, the timber load lines shall be marked in addition
to ordinary load lines. These lines shall be horizontal lines 230
mm in length and 25 mm in breadth which extend abaft unless expressly
provided otherwise, and are at right angles to, a vertical line 25
mm in breadth marked at a distance 540 mm abaft the centre of the
ring (as illustrated in figure 6.2).
(4) The following timber load lines shall be used:
-
(a) The Summer Timber Load Line indicated by the
upper edge of a line marked LS.
-
(b) The Winter Timber Load Line indicated by the
upper edge of a line marked LW.
-
(c) The Winter North Atlantic Timber Load Line
indicated by the upper edge of a line marked LWNA.
-
(d) The Tropical Timber Load Line indicated by
the upper edge of a line marked LT.
-
(e) The Fresh Water Timber Load Line in summer
indicated by the upper edge of a line marked LF and marked forward
of the vertical line. The difference between the Fresh Water Timber
Load Line in summer and the Summer Timber Load Line is the allowance
to be made for loading in fresh water at the other timber load lines.
-
(f) The Tropical Fresh Water Timber Load Line
indicated by the upper edge of a line marked LTF and marked forward
of the vertical line.
(5) Where the characteristics of a ship or the
nature of the ship’s service or navigational limits make any
of the seasonal lines inapplicable, these lines may be omitted.
(6) Where a ship is assigned a greater than minimum
freeboard so that the load line is marked at a position corresponding
to, or lower than, the lowest seasonal load line assigned at minimum
freeboard in accordance with the present Protocol, only the Fresh
Water Load Line need be marked.
(7) Where a Winter North Atlantic Load Line is
identical with the Winter Load Line corresponding to the same vertical
line, this load line shall be marked W.
(8) Alternative/additional load lines required
by other international conventions in force may be marked at right
angles to and abaft the vertical line specified in paragraph (1).
