10 – 12 metres | 8/10mm |
12 – 14 metres | 10mm |
14 – 16 metres | 10mm |
16 – 18 metres | 10/12mm |
18 – 20 metres | 12mm |
You should use about 1/8 inch of chain diameter for every 8 to 9 feet of your boat’s length. The total anchor rode should be 4 to 7 times the water depth. A scope of 7:1 is ideal for most situations.
The International Association of Classification Societies recommends a minimum anchor chain length of 6 to 10 times the water depth. The Royal Yachting Association suggests a minimum of 4 times the depth.
Environmental conditions also affect your choices. Seabed type determines anchor selection. Sandy areas require lightweight anchors like fluke anchors. Rocky areas need stronger anchors, such as plow or Bruce anchors.
Strong currents or exposed locations demand increased chain length and size. Galvanized steel chains provide excellent corrosion resistance in harsh marine environments.
Note: Always inspect your chain and anchor before installation. Adjust chain length for changing water depths and weather patterns.

Installation Process & Safety Checks
A safe installation ensures your complete mooring system performs reliably in all conditions. You must follow each step carefully and check every connection before you finish. Use the following guide to assemble your setup, secure all hardware, adjust for water depth, and complete a final safety inspection.
Step-by-Step Assembly
You can assemble your mooring line and chain setup by following these steps:
Open the 1-meter mooring bungee and remove the carabiner and small foam float.
Position the chain and galvanized quick link at the bottom of your setup.
Cut a 1/2-inch nylon braided rope to the length needed to reach the water’s surface.
Tie the nylon rope to the top ring of the mooring bungie using a bowline knot. Secure the knot with a zip tie.
Thread a rope float onto the top of the nylon rope.
Tie another bowline knot to a stainless steel quick link at the top of the rope.
Attach the mooring line to the anchor eye using the chain and galvanized quick link.
Adjust the length of the mooring line so it matches the water depth and expected tidal changes.
Tip: Always double-check each knot and connection before moving to the next step. A secure mooring line prevents accidental slips and keeps your vessel safe.
Secure Connections
You must ensure every connection in your mooring line is strong and reliable. Follow these best practices:
Attach the end of the bottom chain to the anchor using a shackle one size larger than the chain.
If the anchor neck is large, use two shackles to adapt the fit.
Add a 5/8-inch drop shackle to the bottom of the chain for mooring drop purposes.
Connect the other end of the bottom chain to the lower swivel with a shackle one size larger than the chain.
Attach the top chain to the swivel using a shackle one size larger than the top chain.
Secure the top swivel to the ring with a shackle.
Tighten all shackles and wire them with stainless steel seizing wire.
You should inspect shackles, swivels, and connectors for signs of stress, movement, or corrosion. Replace any worn or damaged parts immediately.
Rinse the chain and hardware with fresh water after each use, especially after anchoring in saltwater. Use a soft brush to remove sand and debris, and let everything dry before storing.
Note: Apply a marine-grade lubricant or corrosion inhibitor to all moving parts. This reduces friction and prevents rust, extending the life of your mooring line.
Adjust for Water Depth
You must adjust your mooring line and chain to match the highest expected tide. This keeps your vessel secure during both high and low tides. Use these guidelines:
Use enough chain and line to accommodate the maximum water depth plus tidal changes.
Follow the general rule of a scope of 2.5 to 3 times the maximum water depth for your mooring line.
Track and label your scope intervals to manage deployment more precisely.
Callout: Always check local tide charts before installation. Adjust your mooring line length if you expect seasonal changes in water level.
Final Safety Inspection
Before you finish, complete a thorough safety inspection of your mooring line and chain:
Check for rust or missing galvanizing. Surface rust is normal, but deep corrosion means you need to replace the chain.
Inspect each link for bending or twisting. Any deformation weakens the chain.
Look for thinning at contact points. If you see a loss of more than 10-15% thickness, replace the chain.
Examine all shackles for wear, corrosion, or damage. Replace as needed.
