The best chain for a boat anchor is typically high-tensile galvanized steel, offering superior strength and corrosion resistance. A proof-coil or BBB chain is ideal for most recreational boats, balancing durability and affordability. For heavy-duty use, G4 or G70 chains provide exceptional holding power and abrasion resistance.

Size: 1/4" to 1" diameter (common sizes for boat anchors)

Grade: Grade 30 (Mild Steel), Grade 43 (High-Tensile), or Grade 70 (Extra High-Tensile)

Viscosity: N/A (Not applicable for anchor chains)

Buoyancy: Negative (steel chains sink in water)

Material: Hot-dip galvanized steel, stainless steel (316 or 304), or proof coil steel

Link Type: Studlink (for strength) or Studless (for flexibility)

Working Load Limit (WLL): Varies by size and grade (e.g., 1/2" Grade 30 chain ~2,000 lbs WLL)

Break Strength: 2-4 times the WLL depending on grade

Corrosion Resistance: High (galvanized or stainless steel preferred for marine use)

Weight: ~1.5 to 10 lbs per foot (varies by size and material)

Standards: Meets ASTM A800, DIN 766, or other marine-grade certifications
