Explanation of Positions

Position 1:

This is the area of the ship that is more exposed to the sea. It includes the forward 25% of the ship’s length from the forward perpendicular (F.P.). In the diagrams, areas marked as Position 1 are typically at the bow of the ship, where they are more likely to encounter severe weather conditions. Structures and openings in this area must meet stricter weathertight and watertight requirements due to their exposure.

Position 2:

This area is less exposed compared to Position 1. It includes the remaining parts of the ship’s deck that are not within the forward 25% length. The requirements for weathertight and watertight integrity are less stringent here because these areas are more protected from direct exposure to the sea.

Diagram Details

• Top Diagram: Shows a ship with multiple decks: Poop deck, Bridge deck, and Forecastle deck. Position 1 is marked at the bow, covering the forward 25% of the ship’s length. Position 2 covers the remaining areas, including parts of the Poop and Bridge decks.
• Middle Diagram: Illustrates a ship with a continuous superstructure deck. Position 1 is again at the bow, while Position 2 covers the rest of the deck.
• Bottom Diagram: Similar to the middle diagram but with a different superstructure configuration. Position 1 remains at the forward 25%, and Position 2 includes the rest of the superstructure deck.

Importance

These positions are critical for ensuring the ship’s safety and structural integrity. The Load Line Convention mandates that ships must have appropriate measures in place for these positions to maintain buoyancy and prevent water ingress, which is vital for the ship’s stability and safety at sea.
