Mastering the art of securing your vessel to the sea floor is an essential skill for any yacht owner. A successful anchoring maneuver demands more than dropping the weight off the front of your boat. It’s important to understand the physics of how an anchor works and to have the right equipment, including an appropriate length of anchor chain and rode, as well as chain markers to keep track of how much chain you’ve let out. In this post, I’ll share my tips and tricks for anchoring in deep waters like those found in the Pacific Northwest.
Anchor Chain and Rode
First and foremost, it is important to understand the concept of scope. Scope is the ratio of the length of anchor chain to depth of water. In the Pacific Northwest, a scope of 7:1 is generally recommended, which means that for every one foot of depth, you should let out seven feet of anchor chain. This ensures that the anchor will be securely set and able to hold the boat in place.
In Puget Sound, where the waters are generally deep, I recommend having 300 feet of anchor chain on boards, with an additional three feet of rode attached to the chain on the opposite side of the anchor attachment point. This allows for greater flexibility in adjusting the scope as needed, and provides an extra layer of protection in case the anchor becomes stuck and needs to be cut loose.
Speaking of cutting loose, it is also important to have a plan in case of emergency. That’s why using a rode instead of an all-chain anchor setup is preferable, as the rope portion can be cut if needed. Be sure to use a knife with a serrated edge that is capable of cutting through rope quickly and easily.
Marking Your Anchor Chain
Marking your chain is crucial for anchoring safely and effectively. I recommend using Osculati Anchor Chain Markers that can be pressed into the chain links and are available in various colors. By marking the chain, you can easily keep track of how much chain you have let out and how much you need to retrieve when raising anchor. To make it even easier, I suggest creating a color chart and changing the color or pattern every 25 feet. (See example above.) When marking the chain, it’s best to put the color designation over one full foot of anchor chain, so it’s easier to see when lowering and raising the anchor.
Anchor Technique
When anchoring, it’s important to find the right spot to drop you anchor. First, search on your navigation chart for designated anchorage areas. Next, look for a spot that is sheltered from wind and waves, and make sure that there is enough room for your vessel to swing in a 360-degree radius. Once you have found the right spot, slowly approach it and stop the boat when you are directly over the spot where you want to anchor. Slowly lower the anchor while paying out the chain and then reverse the boat to set the anchor in the seabed.
By following these tips and tricks, you can anchor safely and securely. Remember to always mark your anchor chain, use the correct amount of chain and rode, and choose the right spot to drop your anchor. With a little practice, anchoring can become second nature, and you can enjoy peaceful nights at anchor in some of the most beautiful waters in the world.
