The bitts are the twin posts used for securing mooring lines. Sailors always found that they made good seats. The chocks are the round openings along the deck edges that mooring lines are passed through to keep them from chafing. Lifelines surrounnd the ship to keep sailors from falling overboard. The lifelines are made of special phosphorous bronze wire.
Stanchions are the posts that support the lifelines.
Snaking is the handmade netting that goes up to the kneeline. It was designed to keep sailors from being washed overboard when the ship plowed under the waves.
