What Is Reefing?
Reefing is a sailing term that refers to reducing the sail area in order to manage the sailboat in high winds.
Reefing involves folding or rolling part of the sail and securing it to the boom or mast to decrease the surface area of the sail exposed to the wind.
This reduces the amount of force on the boat, making it more stable and easier to control.
It is an important technique for any sailor to master, as it can make the difference between a comfortable and safe sail and a dangerous one. It’s one of the first things we learnt to do when sailing, and I wouldn’t go out on any sailboat without knowing how to reef the sails first!
In this guide, we will explore the basics of reefing and provide tips and techniques for successful reefing.
When Should You Reef A Sail?
Reefing a sail is an important skill for sailors to have, as it helps to control the sail’s surface area in strong winds. But when exactly should you reef a sail?
The answer to this question depends on various factors, such as the strength of the wind, the type of boat and sail, and the experience and comfort level of the sailors on board.
As a general rule, most sailors will start reefing their sails at around 18knts of wind. If you’re sailing a smaller, lighter vessel then you might need to reef earlier. If your boat is a heavy, slow boat then it might be able to handle stronger winds.
Our heavily built sailboat can handle slightly higher winds, more like 20 knots. But we will usually play on the side of caution and reef earlier anyway. It’s always better to be safe when conditions are picking up.
You should always take into consideration the comfort of your crew, too. Your boat might be sailing along nicely in 15 knots without a reef, but if it’s heeling significantly and your crew are nervous and uncomfortable then you should put their ease ahead of speed.
Obviously when things get really spicy out there you’re going to want to know what to do. Sometimes putting reefs in the sails isn’t enough, and you’ll need to learn proper storm tactics like how to heave to or use a storm sail.
How Do You Reef While Sailing?
Each boat has a slightly different reefing system so before you head out sailing on an unfamiliar vessel you should make sure you know how to reef the sails.
That being said, most sails are reefed in a very similar way, so here is a basic guide to reefing your headsail and mainsail.
How To Reef A Mainsail
Reefing a mainsail while sailing can be a bit challenging, but it’s an essential skill for any sailor to learn. The process of reefing involves reducing the sail area to help control the boat in strong winds. This is done by partially lowering the mainsail and securing it to the boom and mast using reefing lines.
To reef a mainsail while sailing, the first step is to ease the mainsheet to depower the sail. You’ll want to head up into the wind to take pressure off the sail, so make sure everyone knows you are about to reef so they can help or get out the way!
Once the boat and boom are in a safe position, the reef can be put in. To do this, take tension off the main halyard and lower the sail to the first, second, or third reef. Then attach it to the hook or ramshorn at the foot of the boom.
You have now effectively shortened your sail. But it’s probably flapping around all over the place! Time to get some tension on.
First, raise the halyard. You’ll see your sail is much shorter now, with a reduced sail area. Then take tension on your reefing line (hopefully these are labelled so you know which to tension). This will tighten the foot of your sail.
Lastly, trim the sail by adjusting the mainsheet and traveler to ensure the boat is sailing efficiently with the reduced sail area.
You might also need to adjust the topping lift now that your sail is smaller and lighter.
It’s important to practice reefing a mainsail in moderate conditions before encountering stronger winds, as it can be a challenging task in rough weather. Adam and I tend to reef our mainsail early if we’re beating upwind, as the design of our boat means we need to go up to the mast to reef.
When the sea picks up this can feel pretty dangerous, so if we foresee this happening we stick a reef in just in case and put up with sailing slower.
With a lot of boats these days you can reef from the cockpit, making everything much safer and easier, especially for the single-handed sailor.
Proper preparation and practice will help ensure you’re able to reef the sail safely and efficiently when the need arises.
How To Reef A Headsail
Reefing a headsail, or furling it, can be a bit easier than reefing a mainsail. Here are the general steps to follow:
- First, decide how much you need to reef the sail. If you have a roller furling headsail, this may be as simple as rolling it up a bit. If you have a hank-on headsail, you will need to remove the hanks from the appropriate reefing points.
- Turn the boat into the wind to take pressure off the sail. Make sure the headsail is completely luffing (flapping back and forth) before you start reefing.
- Begin furling the sail or removing the hanks as needed. If you have a roller furling headsail, use the furling line to roll up the sail to the desired reefing point. If you have a hank-on sail, remove the appropriate hanks and retie the sheets to the reefing points.
- Once the sail is reefed, trim the sheets to the appropriate angle and adjust the jib lead if necessary.
- Resume your course and adjust the sail trim as needed.
It’s important to note that reefing a headsail may not be necessary for all sailing conditions, and the specific steps may vary depending on your boat and equipment. The great thing about a furling headsail is that you can keep reefing and reefing until you’re just flying a tiny triangle.
The downside is that reefing a headsail does usually mess with its shape a little bit, especially if it’s older. We’ve never had a problem with this.
If we need to reef then the wind is usually strong enough that we aren’t worried about getting maximum performance and more worried about safety!
Which Sail Do You Reef First?
Generally, it is recommended to reef the mainsail first and then the jib sail. This is because the mainsail is usually larger and more difficult to handle than the headsail, and it can have a greater impact on the boat’s stability and handling if left unreefed in strong winds.
It’s also usually the hardest sail to reef, as you often have to go up to the boom which isn’t always desirable in rough seas.
However, the exact order of reefing can depend on various factors, such as the boat’s design, the sail configuration, and the sailing conditions.
For example, our genoa sail is absolutely massive. We will sometimes reef this first, especially if the wind isn’t forecast to pick up and the conditions are changeable. It’s far easier to put reefs in and shake them out on a furling headsail.
This is where knowing the boat you’re sailing can be a real benefit.
What If The Sails Are Already Fully Reefed?
If you’ve fully reefed your sails and the boat is still overpowered then don’t just sit and do nothing!
If you continue to sail with an overpowered rig then all sorts of things can go wrong, including your sails ripping (you don’t want to know how much new sails cost) and even getting dismasted.
If the wind is so strong that you can’t continue sailing on your current reefed sails then you need to take them down and put up your storm sail. This is a small and rugged headsail that you can hank on for really rough conditions.
Again, this isn’t something you should be using for the first time in anger. You need to know how your storm sail works, have it easily accessible and be well versed at fitting it.
If you are still overpowered or you don’t have a headsail then you will be best off doing one of a few things, depending on the type of boat you’re sailing, where you are and your experience level.
- Sail on bare poles alone. Some boats will keep sailing relatively well without any sails up if the wind is strong enough. The type of boat, wind conditions, and sea state will all dictate whether this is a good idea.
- Heave to. If you’re sailing in storm conditions then heaving to is almost always a good idea. The boat will ride nicely over any waves and you will make hardly any headway, meaning you can go and make a cup of tea below while you wait out the bad weather.
- Motor. If you’re in an enclosed bay or close to land then you might be best off motoring to a safe anchorage or marina. Using a sailboat without sails is sometimes the best option. Adam and I have done this more than once!
Conclusion: Reefing A Sail
Reefing a sail can be a crucial skill to have as a sailor. Knowing when and how to reef can make the difference between a safe and enjoyable sailing experience and a dangerous one.
It is important to remember that every boat and sailing condition is different, and there is no one-size-fits-all approach to reefing. You should have a rough idea of the kind of wind speed the boat your sailing will need to reef in, but you should also pay attention to how much your boat is heeling and how comfortable your crew are.
Whether you are a beginner or an experienced sailor, taking the time to practice and learn the different reefing techniques can help you become a more confident and skilled sailor.
