2.1 the Summer load line, when the ship is in a Summer Zone, excluding any part of such a zone which is a seasonal area in relation to the ship;
-
2.2 the Tropical load line, when the ship is in a Tropical Zone;
-

-
2.4 the Winter North Atlantic load line, in the case of a ship of one hundred metres or less in length, when it is in these zones during the Winter seasonal periods applicable to them —
2.4.1 North Atlantic Winter Seasonal Zone I, as set out in paragraph 4.1;
2.4.2 North Atlantic Winter Seasonal Zone II, as set out in paragraph 4.2 as lies between the meridians of longitude 150W and 500W,
-
during the winter seasonal periods applicable in those zones;
-
2.5 the Summer load line, in the case of a sailing ship, except in circumstances in which subparagraph 2.4 applies;

Ports on Boundary Lines
3. For the purposes of applying the provisions of this Schedule to a ship at a port which stands on the boundary line between two zones or areas or between a zone and an area, or which is required by this Schedule to be considered as being on such a boundary line, the port is deemed to be within the zone or area into which the ship is about to proceed or from which the ship has arrived as the case may be.
