Chain and rode refer to the combination of anchor chain and rope used to secure a vessel. Anchor chains are heavy-duty metal links that provide strength and weight to hold the anchor in place. The rode connects the chain to the boat, ensuring stability and flexibility during anchoring.

Size: Typically ranges from 10 mm to 130 mm in diameter.

Grade: Common grades include Grade 2, Grade 3, and High-Test (Grade 30), with varying tensile strengths.

Viscosity: Not applicable, as chains are solid metal components.

Buoyancy: Negligible, as chains are denser than water and do not float.

Material: Usually made of high-strength carbon steel or alloy steel, often galvanized for corrosion resistance.

Length: Standard lengths vary, with common rode lengths of 50-300 meters depending on vessel size.

Weight: Approximately 10-300 kg per meter, depending on size and grade.

Breaking Load: Varies by grade and size, ranging from 5 to 3,000 metric tons.

Certification: Often complies with international standards like ISO 1704 or ABS/DNV/GL classifications.
