Why do boat anchors have Anchor Chain? 

The Anchor Chain is a vital component in mooring a ship to the bottom. Along with the anchor, the chains weight holds the vessel in place. The amount of chain used is very important, because too much will allow the ship to move around excessively and too little may allow the ship to drag its anchor.

What size chain for my boat anchor? 

Anchor Chain Size Rule of Thumb

There is an old rule of thumb that dates back many years, which states a requirement of 1/8" chain diameter for every 9 or 10 feet of boat length - with approximate metric conversions:

e.g. 1/4" now available as 6mm DIN766 chain would be up to 20 or 23 feet Yacht LOA, 7mm DIN766 chain would be up to 23 or 27 feet Yacht LOA, 5/16" now available as 8mm DIN766 would be up to 27 or 31 feet Yacht LOA, 3/8" now available as 10mm DIN766 and 10mm ISO4565 would be up to 34 or 39 feet Yacht LOA.

Although modern yachts are generally designed and built with lighter, technologically advanced materials, they are often kitted out with a lot more equipment to add the weight back on, and the current trend is towards heavier anchors with much higher holding power, which will inevitably lead to higher loads on the anchor rode.

Grade 40 Calibrated Anchor Chain is 25%+ stronger than Grade 30 Anchor Chain providing extra assurance when conditions worsen and your yacht is caught on a lee shore.

How much Anchor Chain and Rope do I need?

This works for the middle range of anchorage depths but starts to look a little out of kilter as you approach either end of the scale e.g.

 ● 8:1 in 3 meters of water equates to 24 meters total rode length, which is possibly not a satisfactory anchoring solution in anything but benign weather

 ● 8:1 in 5 meters of water equates to 40 meters total rode length, which may be adequate for Inshore and Coastal hopping

 ● 8:1 in 20 meters of water would be 160 meters of total anchor rode, which would seem a little over the top!

However, Scope 8:1 for 10 meters of depth = 80 meters total chain and warp and this makes a good benchmark starting point for your final decision.

For extended Offshore and Ocean cruising, consider increasing the scope to 10:1 on all chain or even 12:1 on a chain/rope combination.  This particularly applies to anchorages around some Pacific islands.

ANDY MARINE chains help the proper functioning of your Anchor Rode. With their weight, they generate the proper Scope. The correct Scope is essential for the proper functioning of the Anchor by creating a downward pull on the anchor handle, referred to as the Shank. Helping the rode line pull horizontally, rather than be pulled upward and loosen the Anchor. Protects your nylon line from debris or other sharp objects underwater that could lead to a cut line and anchor loss. Works on all windlasses brands. Ideal for anchoring on vessels from kayaks, Pontoon, Fishing, Sailing, and Cruising boats. Using a chain on any anchor is essential for the entire anchoring system. Decades of anchoring research and testing prove how crucial are the chain leads as part of the anchor lines.
