Marine Structures and Terminology

A canopy made of canvas offers shelter over a vessel's decks, protecting against sun and weather elements. This is essential for crew comfort and equipment preservation.
Acute angle bending refers to altering one flange of a bar to form an angle smaller than 90 degrees with the other flange. This modification can affect structural integrity and load distribution.
A black tar-like composition serves as a protective coating in various marine applications, particularly in areas like ballast and trimming tanks, chain lockers, and shaft alleys to prevent corrosion and wear.
Obtuse angle bending describes the process where one flange of a bar is bent to create an angle greater than 90 degrees with the other flange. This technique can be used for specific design requirements or structural enhancements.
A single sheave block features one side of the frame that is hinged, allowing easy access to place the bight of a rope onto the sheave. This design facilitates quick rigging and adjusting in marine environments.
