Which structural members extend athwartships and are attached to the keel?

Explanation:
Frames are the transverse hull members that run from one side of the ship to the other and are attached to the keel along their lower edge. They provide the cross-sectional shape and strength of the hull, acting like ribs around the backbone. Decks are horizontal floors that span between frames and sit above the keel, not across it. Stringers run lengthwise along the hull to stiffen the structure, not across the width. So the transverse members attached to the keel, forming the hull’s cross-sections, are frames.
