CHOOSING THE CORRECT ANCHOR RODE

Advice on how to select the correct anchor line and chain rode for your boat.

Whitsunday Discount Marine recommends 3 strand nylon rope for anchor line due to its stretch and strength. Silver or polypropylene rope is not recommended.

 

Nylon 3 Strand:

1.4mm of rope diameter per meter of boat length

 

Chain length = boat length (preferable)

Chain diameter:

8mm anchor line:                     6mm chain

10mm anchor line:                   8mm chain

12mm anchor line:                   8mm chain

14mm anchor line:                   8mm chain

16mm to 20mm anchor line:   10mm chain
