keelamist

A keelamist is a craftsman or engineer who specializes in the keel of a vessel, the principal structural element that runs along the bottom of a hull. The term is uncommon and most often found in historical texts, shipwrights’ glossaries, or in discussions of traditional wooden shipbuilding. In essence, a keelamist is concerned with the design, fabrication, alignment, and maintenance of the keel and its connections to the rest of the hull.

In wooden shipbuilding, the keel is laid as the first major frame and serves as the backbone for the vessel. A keelamist would ensure the keel's straightness, plumb lines, and proper attachment to the keelson, stem, and stern posts. The work involves coordinating with frame builders, caulking teams, and later plating or planking crews to guarantee a sound foundation for the hull.

Materials and forms vary by era and vessel type. Traditional keels were heavy timber, often extending the full length of the hull; modern vessels use steel or reinforced concrete or composite keels in certain ship types. In sailing craft, the keel contributes to stability and tracking, while in some ships the keel also provides ballast housing and ballast distribution.

Today the specific title "keelamist" is rare, with related responsibilities typically held by shipwrights, naval architects, or marine engineers. The concept remains relevant in discussions of historical ship construction and in the maintenance of heritage vessels.
