Picking the Right Anchor Chain for Your Cruising Boat
Boats that are already installed with windlass, it's crucial to pick out the proper chain in terms of style and size; the gypsy on the windlass should be compatible with the anchor chain. This goes both ways, those contemplating a windlass have to be sure that the gypsy is suitable for the chain that's already present on the boat. Take note that every manufacturer of windless come with certain chain gypsies on the windlasses.
Types of Anchor Chains
Three basic types of galvanized chains are available and commonly used when involving cruising boats. First is similar to the galvanized chains you'll usually see in common chandeliers called proof-coil chains. It features a long ling that's not all that durable but is has numerous uses offshore and onshore. Out of all the galvanized chains, proof-coil chains are the most budget-friendly. G-3 is tamped on every link so it's simple and easy to identify. Although not that many cruisers opt for the proof-coil chains, many windlasses are available in accommodating the G-3 chains. General usage of the proof-coil chains involve ground tackles, especially when the owners is limited to a meager amount of anchor chain backed up by nylon lines.
Triple B chains are the next type of galvanized chains and they are also the preferred type. Just like proof-coil chains, each link on this chain displays either 3-B or BBB. With its durability, the Triple B chains are sold at moderate prices and could be seen on the majority of cruising boats.

Last is the galvanized chain marked with HT or G-4 which is known as a high-test chain. Compared to the aforementioned chains, these are a lot stronger but at the same time a bit more expensive due to the level of durability and quality it possesses. Cruisers of varying shapes and sizes go for the G-4, especially of the weight is a considerable factor and chain lockers are limited in terms of space. G-4 with smaller diameters could also be used; even with the reduced diameter, they're still stronger than the bigger versions of BBB links.
Keep in mind that as you choose the ideal anchor and chains for the boat's windlass or the boat itself, the diameter remains to be the critical factor. Majority of cruising boats nowadays use G-4 measured at 5/16 inches or the Triple B chains at 3/8 inches. Of course there are smaller and larger links available for each type of anchor chain.
