What is a BBB anchor chain?
BBB anchor chain - or 3B as it's also known - is certainly a good choice of anchor chain because it's calibrated for use with most modern anchor windlass gypsies (aka 'wildcats'). It may be the most commonly used anchor chain on cruising boats, but it's not the only choice...
Can you use proof coil chain with anchor windlass?
Proof Coil chain is not calibrated , and is therefore unsuitable for use with anchor windlasses. However, it's perfectly suitable for rope/chain anchor rodes for small boats - providing you're happy to haul it in by hand.

What is the difference between a HT chain and a BBB chain?
The the difference between HT/G43 and BBB Chain (and other chains) is simple: these chains have different dimensions. While it may not sound right that 1/4" HT chain and 1/4" BBB Chain have different measurements as they’re both called quarter inch, but in reality these chains' width, length, and pitch and vary greatly. See the diagram below. It should be pointed out that different types of chain often have different breaking strengths as well, but for most boating applications, the main concern is the dimensional difference.
What chain does a windlass use?
Almost all windlasses accept either HT/G43 Chain (note, HT Chain is sometimes referred to as G40, G43, or G4 chain which all work interchangeably) or BBB chain, with nearly all new windlasses requiring HT/G43 Chain. If you go to purchase chain and it does not clearly say that it is HT/G43 or BBB, it likely is not.
Why is my anchor shank bent?
Numerous factors can ultimately lead to a bent anchor shank, but the majority of the time this is caused either by a bad snag or from the boat shifting its load in a perpendicular direction from the anchor set. In this article, we will discuss common causes and prevention tips to help you avoid finding yourself in such an unlucky predicament.

The links of the chain are formed from low carbon steel wire, and the size of the link is actually referring to the size of the wire that was used.
What is the breaking strength of a BBB chain?
The interesting thing to note is that the breaking strength is 4x grater than the working load, giving this type of chain a significant safety margin. When the chain is manufactured, it is then subjected to a rigorous test of strength, followed by a close inspection of each individual link. This strict quality control set BBB chain apart from other link forms that were in production at the time.
