What is companionways?

Companionways are vertical stairs attached to the deck or cabin top of a boat or yacht. They provide access to the interior of the boat from the deck or cockpit and also provide ventilation and light. Companionways may be made of different materials such as wood, fiberglass, or metal, and they may have various configurations and designs. They can be open or enclosed and may have hinged or sliding doors to provide security and privacy. Companionways can be an important safety feature as they allow for quick and easy access in emergencies. It is important for companionways to be kept clear and for safety handrails to be installed to prevent falls.
