A cheek block, also known as a turning block, is a type of block designed to be mounted on a flat surface, allowing a rope or line to run parallel to that surface.
Understanding Cheek Blocks
Cheek blocks are fundamental components in various rigging systems, particularly in sailing and boating. The key characteristic that defines a cheek block is its mounting style - it affixes directly to a flat surface, unlike some other blocks that may attach to a stanchion or have a hanging setup.
Key Features of Cheek Blocks
-
Flat Surface Mounting: This is the defining characteristic. They are designed with a flat base that allows them to be screwed or bolted onto a deck or other flat surface.
-
Parallel Line Run: Cheek blocks redirect a line so that it runs alongside the surface to which the block is attached. This is crucial for managing lines efficiently and safely.
-
Versatile Applications: They are used in multiple contexts, as highlighted in our reference:
- Sheet Blocks: Used to guide the sail sheet.
- Foot Blocks: Used near the base of a mast to guide control lines.
- Deck Organizer Blocks: Used to direct multiple lines towards winches, clutches, or other control points.
Practical Insights and Examples
Example Uses
-
Sailboat Rigging: On a sailboat, a cheek block might be found directing a genoa sheet to a winch, or a control line towards a clutch.
-
Material Handling: In non-maritime settings, cheek blocks can be used to direct cables or ropes in industrial settings to move heavy objects.
Why Use Cheek Blocks?
- Efficiency: They allow for better management of lines, preventing tangles and friction.
- Safety: By controlling the direction of lines, they improve safety and control during operations.
- Durability: They are typically made from robust materials to withstand the stresses of the rigging system.
How to Install
- Select a flat surface: Choose a solid, flat surface where you need to redirect the line.
- Position the block: Place the cheek block where you need it, ensuring it's aligned correctly.
- Securely attach it: Use appropriate screws or bolts to mount the block to the flat surface, ensuring a firm connection.
- Run the line: Feed the rope through the block, ensuring smooth movement.
Conclusion
In essence, a cheek block is a type of block specifically designed for flat surface mounting to redirect a line in a parallel direction. This feature makes them indispensable for a wide range of applications, particularly in sailing where they serve as both sheet and foot blocks, and as part of the deck’s organization system.
