Marine weathertight doors, also known as semi-watertight doors, are divided into metal and wood. The structure of the metal weathertight door is similar to that of the metal watertight door, but the weight of the door plate is slightly lighter, the wedge handle is less, and the amount of sealing filler pressed into the door is shallower when closed, and the requirements of the corresponding tightness test should be met to ensure that it is impervious to water under any wind and waves; the use of wooden doors should also ensure that they are resistant to waves and water impact. It is generally used as the cabin door leading to the open air of the deck room on the freeboard deck, as well as the door of the engine and furnace room, the door of the storage room, the door of the food room, etc. Open to the open kitchen, double and half doors are available. When considering exterior decoration, wooden doors can be used.
