3.21

weathertightness

capacity to prevent that, in any sea conditions, water will penetrate into the ship

Note 1 to entry: This definition has been adapted from the term “weathertight” taken from the International Convention on Load Lines (ICLL), Annex I, Regulation 3 (12). This is interpreted generally as indicating that weathertightness is required from the exterior only, as opposed to watertightness (3.22) , indicating the ability to withstand from both inside and outside.

3.22

watertightness

capacity of an appliance to prevent the passage of water through the structure in any direction under a head of water for which the surrounding structure is designed
