- Shell plating
Shell plating is the outer-most structure on the hull of a
steelor aluminum shipor boat. It is the structural element that renders the hull watertight.
strakeis the name given to each line of planking in a wooden vessel. [Kemp, "The Oxford Companion to Ships and the Sea" , p. 838 (definition of 'strake').] In modern ship construction it refers to the longitudinal run of plating covering the hull, deck and bulkhead structure. Certain specific strakes are uniquely identified:
Keel : is a special strake of the Bottom plating extending from the centerplane outboard.
Bottom : the Bottom Shell plate strakes extend from the Keel to the Bilge.
Bilge : is the plating which transitions from the more-or-less horizontal Bottom Shell to the more-or-less vertical Side Shell and is generally curved. See also
Side : is the plating which extends from the Bilge stake(s) to the Shear strake.
Shear : is a special strake of the Side plating. It is the strake that connects the Side Shell to the Strength Deck.
Stringer : is a special strake of the Strength Deck plating. It is the strake that connects the Strength Deck to the Side Shell.
Strength Deck : is a special deck. It is normally the uppermost continuous deck and forms the top flange of the hull girder. See
