How should timber deck cargo be stowed for the alternative intact stability regulations to apply?

Timber deck cargo must be stowed as solidly as possible and should ideally extend over the entire length of the weather deck for the alternative intact stability regulations to apply. This method of stowage ensures a more uniform distribution of weight along the deck, which is critical in maintaining the vessel's stability during navigation. A solid stowage arrangement minimizes the risk of shifting cargo, which can lead to a reduction in the vessel's metacentric height (GM) and overall stability.

When timber is stowed properly, it helps to prevent concentration of weight on one part of the vessel, thereby reducing the likelihood of excessive list or trim that can arise from uneven loading. This is particularly important in scenarios where the vessel may encounter rough seas or varying weather conditions, as proper stowage contributes to the ship’s ability to withstand dynamic forces effectively.

The requirement for extending over the entire length of the weather deck further adds to stability by ensuring that the center of gravity remains as low as possible in relation to the center of buoyancy, which is a key element of good vessel stability practices.
