Mooring chains for narrowboats are durable, heavy-duty chains used to secure boats to fixed points along canals or rivers. Anchor chains are robust chains designed to connect anchors to boats, providing stability and security in various water conditions. Both types are typically made from galvanized steel to resist corrosion and ensure long-lasting performance.

Mooring Chains for Narrowboats:

- Size: Typically 8mm to 16mm diameter

- Grade: Grade 30 or Grade 40 (common for inland use)

- Material: Galvanized steel or stainless steel

- Buoyancy: Minimal due to metal density

- Viscosity: Not applicable (solid metal)

- Working Load Limit (WLL): Varies by size (e.g., 10mm chain ≈ 1.5-ton WLL)

- Standards: EN 818-2 or ISO 1704 (for short-link chains)

Anchor Chains:

- Size: 6mm to 20mm diameter (larger for heavier vessels)

- Grade: Grade 30, 40, or 70 (higher grades for marine use)

- Material: Hot-dip galvanized steel, stainless steel, or proof coil

- Buoyancy: Negligible (sinks in water)

- Viscosity: Not applicable

- Working Load Limit (WLL): Depends on grade/size (e.g., 8mm Grade 40 ≈ 1.8-ton WLL)

- Standards: ISO 1704, DIN 766, or ABS certification
