8 Steps To Anchoring In A Storm

So, what do you do if a storm is on its way and you’re anchored in a harbor? Anchoring in a storm or high winds is part of the sailing lifestyle. Many storms arrive unannounced, and others, although predicted, can be worse than expected.

Use these eight steps to anchoring in a storm. As a sailor, it's important to understand key steps to ensure your boat and crew are safe. Click To Tweet

After reading the steps, watch our video, located below, showcasing A Big Blow in The Bahamas.

For three days we were anchoring in a storm with winds of up to 45 knots and gusts well over 50 knots. The video also shows a catamaran dragging and important information about how we handled the high winds.

8 Steps To Anchoring In A Storm

1. Analyze your surroundings

Survey your current anchor spot and determine if it makes sense to move the boat to another safer anchorage or another spot within the anchorage. There are many factors to consider when analyzing the safety of a harbor, especially when a storm is on its way.

Ideally, when it hits, you want the wind to blow you away from land and/or any obstructions (rocks, shallows, etc.) in addition to having good holding for your anchor. Look at the forecasts to determine if the wind direction will change and if you can safely swing on your anchor.

Another key consideration regarding anchoring in a storm is the number of boats in the anchorage.

With more boats, there are more chances of another boat dragging and hitting you. There’s also the position within the anchorage to consider. If you anchor close to shore and drag, how many boats will you take out on your way? Or what happens if you get your anchor line fouled in another line?

TIP: We usually anchor the furthest away from land and other boaters in a harbor. We feel that if things get really bad, our best bet is to up anchor and head out into sea away from other boats, land, etc. The downside of doing so is that the wind can often be stronger as there’s less protection from the land.

2. Dive on your anchor.

Wherever you decide to anchor, if it’s possible, make sure to dive down to visually ensure that it’s bedded in. Later, when the storm hits this action will provide a higher degree of comfort. In many cases, it’s impossible to do a visual inspection, but if you could have done it and didn’t, you’ll regret it when the winds start blowing.

When diving, make sure that the anchor is set well. Also, take note of the seabed. If you’ve anchored in the grass or around grass, you might want to switch to an alternative anchorage. When dragging in the grass the anchor often gets filled with grass and mud preventing the anchor from resetting.

Important note: Many sailors fail to understand the art of anchoring. I think that people assume it’s easy or that it’s just one of those things that come naturally?! If you have any doubt about your knowledge of anchoring and/or whether or not your ground tackle is correct for your boat, this is one aspect where ignorance is not bliss.

Get my step-by-step checklist on anchoring in my guide, Checklists for Sailors. Not only will it decrease your likelihood of dragging, but it will also provide you with increased peace of mind that you prepared properly.

3. Let out enough scope when anchoring in a storm

If you’re happy with your current location and you’ve done your best to verify that the anchor is well set, the next step is to consider your scope. The scope is the ratio of anchor rode (anchor chain or rope) let out according to the depth of water you’re in, considering your freeboard (length from the deck to the waterline). Most sailors use a ratio of around 3 to 5 times the depth in calm weather. So, if you’re in 15’ of water (including freeboard), you’ll let out 75’ of rode using the 5x ratio.

When you originally anchored, if your scope was between 3x to 5x the depth, you’ll want to increase that figure. Many sailors will aim for a 7x to 8x scope during storm situations if doing so does not put the boat in danger. The key concept is that more rode causes more of a horizontal pull on an anchor, and less rode causes a vertical pull.




During a storm, the wind causes the anchor rode to pull back, and waves cause it to jostle up and down. The more rode that’s out, the less likely that it will pull up and out.

And if the anchor does pull out, with more rode, you’ll have better chances for it to drag rather than get pulled through the water. In other words, if the anchor drags, it’s more likely to reset itself, provided enough scope is used.

However, it’s important to note that too much scope is not necessarily good either.

Too much rode can put you dangerously close to obstructions. Furthermore, in really high winds, your boat can start to sail. We’ve seen boats sail right off the anchor due to too much rode out!

In short, before a storm hits, ensure that you have a scope that is suitable.

4. Ensure you have a snubber, or bridle, attached with anti-chafing guards.

If you don’t have a snubber or bridle and plan on anchoring your boat often, you’ll need to put that on your shopping list as a number one priority. Time after time, I see boats without snubbers and can’t believe my eyes.

A snubber takes the load of the ground tackle, wind, and current off the windless mechanism (the thing that pulls the chain in and out) and places it onto the hull, or superstructure, of the boat.

The windlass is just a tiny bit of kit. You wouldn’t want something so small to hold the boat’s weight, would you? Using a snubber, you effectively create a small bit of slack in the anchor chain, removing any pressure on the windless. The load is then transferred onto strong points on the boat’s hull.

Again, if you’re not accustomed to using a snubber, get my anchoring guide, as it’s vital equipment. Within the guide, I offer information on how to use a snubber.

Additionally, when anchoring in a storm, the snubber can move about over the top of the anchor chainplate. There’s a high chance of chafing, so using anti-chaffing guards is vital. If you don’t have chafe guards, you can wrap areas of the snubber with heavy-duty tape.

5. Check that your anchor alarm is set

Use a couple of anchor alarm systems to ensure you’re covered. We use our built-in GPS anchor alarm system and an Ipad anchor alarm app (We use SafeAnchor.net). When our alarm goes off, we know it’s time to act.

Anchor alarms allow you to program the position of your anchor and then set the radius you’re happy to swing within. If the boat goes outside the circle’s circumference, the alarm will trigger.

In 99.9% of the cases, our alarms are triggered due to naturally swinging outside the limits we set, but it’s better to be safe than sorry. If you’re dragging, you want to know as soon as possible.

6. Reduce the amount of windage on your boat

Before the storm hits, remove anything that will catch the wind and increase the load on the anchor tackle. Pull down your sprayhood, bimini, cockpit enclosures, and so forth. Not only will this protect them from tears or blowing off, but it will also provide your anchor with a higher chance of holding.

7. Decide upon an anchor watch system

When anchoring in a storm, if it’s going to blow and you’re in a crowded harbor, it might be worth setting a watch rotation. We often do three hours on and off all night, similar to our night sailing watches. On an anchor watch, you’re ready to respond in the case of dragging, and, often, more importantly, you can see an oncoming boat dragging towards you. We’ve had many boats drag in front of us and behind us, and a few have even hit us. Luckily, we were always on sight to use fenders to fend the boat off or work with the other boat owner to find a solution.

8. Have anchor faith

If you have loads of time before a storm hits (perhaps you’re reading this before you’ve even purchased a boat?!), my biggest advice is to understand your anchor system. Find out how your anchor ranks in the world of best-setting anchors for the seabed you plan on anchoring in. Research the areas you plan to anchor and ensure you have enough rode or chains.

Side story: Our good friends purchased a boat and set sail for the Bahamas. By the time they got to Georgetown, they had anchored a couple of times and had already realized their anchor was inadequate. Having a Bruce anchor, they dragged time and time again. When The Big Blow of 2018 hit, they had three sleepless nights. Thankfully, they didn’t drag during the high winds, but they did drag at other times. As soon as they reached Puerto Rico, where they could source a new anchor, they purchased a Rocna.

Nothing is worse than being stuck on a boat in high winds for 48 or 60 hours, not having anchor faith. To reduce fear and be able to sleep at night, you want to know that you have an anchor that will keep you safe.

And if you don’t already have a Mantus Anchor or a similar new breed of more advanced anchors, do yourself a favor and get one. Whenever I freak out, my husband looks at me and says, ‘Kim, we have the best anchor in the world. We have a Mantus.’

Sailing and the sailing lifestyle are most exciting, enjoyable, and fulfilling.

However, some bits and pieces suck. And I mean, suck. Being at anchor in a storm or a hurricane is scary. If you’re going to be a boater, storms happen. When a storm hits, you want to know that you’ve done the best you can.

Out of the millions of things a boat owner can purchase, it can be confusing as to what’s a necessity versus what’s nice. Having a plotter that provides a touch screen or a new-fangled techy gadget is not a necessity! Having a sound ground tackle system is.

We’ve come across loads of boats with all sorts of bells and whistles, and then you look at the anchor and notice that it’s an old-generation anchor (like a Bruce, Delta, or CQR). What the heck?! Priorities people. Priorities.

But sailing, sailboats, and the sailing lifestyle are overwhelming to newcomers. I’ve done this full-time for six years and still consider myself wet behind the ears. We don’t know what we don’t know.
