Features:

Material: Towing chocks are typically made of durable materials such as steel or cast iron to withstand the harsh marine environment and the substantial forces involved in towing operations.

Mounting: Towing chocks are securely mounted on the deck or hull of a vessel, often near the stern or bow, where towing operations are most likely to occur.

Types of Towing Chocks:

Panama Chock: These are used primarily on ships passing through the Panama Canal, designed to handle the heavy towing lines and prevent damage.

Closed Chock: This type provides a closed loop, offering more security for the towing line, preventing it from slipping out.

Open Chock: An open design that allows for easier placement and removal of the towing line but requires more careful monitoring to ensure the line doesn't slip out.

Maintenance:

Inspection: Regular inspections are necessary to check for wear and tear, corrosion, and any structural damages.

Lubrication: Some towing chocks may require lubrication to ensure smooth operation and reduce friction.

Cleaning: Keeping the chock clean from marine growth, dirt, and debris is essential for maintaining its functionality.
