Kelson

• The kelson or keelson is the member which, particularly in a wooden vessel, lies parallel with its keel but above the transverse members such as timbers, frames or in a larger vessel, floors. It is fastened to the keel partly to impart additional longitudinal stiffness to it but principally to bind the longitudinal members (keel and hog) to the transverse members (frames and floors).
