“ [Strakes) specifically refer to the bottom and side shell plating which are the supposed points of maximum stresses. Strakes are categorized as Bottom Strake, bilge strake and Sheer Strake. The bottom shell plating follows a unique system of nomenclature in almost all ships,i.e. in the form of successive alphabets with the keel as reference (e.g. A strake, B strake etc.).
“The first strake in the order of appearance is also termed as Garboard Strake.
“Similarly, the strake situated at the "turn of the bilge" is referred to as the Bilge Strake.
The upper-most strake near the deck edge is the Sheer Strake. It may be worth saying that as these are the critical points of high stresses, additional strengthening is provided to these plating to sustain high amounts of unpredictable loads.
“Other members: Even if the ship looks complicated, its structural components are not that much complicated or massive as they might seem.The items are very basic like columns, struts, beams, flanges, angles, brackets and stanchions. Maybe these are not all. Small to negligible members exist in every minuscule of the vessel to give rise to the proper functionality of the structure. The nomenclature of all such members are different according to their role and location.Their role may be variant in the either of the following forms:
Construction, Support, Strengthening, Stiffening”
