When to reef? The first time you think about it
The rule is as old as sailing itself and in 25 years of charters I have never found an exception to it: reef the first time the thought crosses your mind. Not "in ten minutes", not "after this tack", not "if it picks up some more". If you have thought about reefing, it means the wind is already at the limit. And in Masuria that limit can shift within minutes, because a summer squall arrives faster than you can sort out the main halyard.
The best reefing is the kind nobody sees, because you did it back in port or on calm water in the lee of a forest. A reef put in too early is easy to shake out. A reef put in during a squall is a fight with flogging canvas, a heeling deck and your own nerves.
What a reef actually is
A reef is simply a reduction of sail area. A smaller sail catches less wind, the yacht heels less, the helm gets lighter and the crew stops sitting on the rail with white knuckles. On a typical Masurian charter sailboat you have two things at your disposal: reefing the mainsail and rolling up the jib on a furler. The main usually has one or two reefs, meaning two "storeys" you can shorten it by.
An important point for beginners: a reefed yacht in strong wind does not sail slower at all. It sails faster and straighter, because it is not lying over on its side and not fighting the helm. Heel beyond a certain angle is pure loss: the hull drags, the rudder stops holding a course, and the sails do not work well anyway.
How to reef the mainsail
Depending on the yacht you will come across two systems. If you do not know which one you have, ask at check-in. Seriously, that one question saves a lot of stress later.
Reef points, the classic way
The sequence is always similar. Put the bow close to the wind line, most conveniently under slow engine so the main is not drawing. Ease the main halyard and lower the sail to the height of the reef cringle. Secure the tack cringle at the boom and tension the halyard again. Only then haul in and tension the reefing line of the clew cringle. Finally gather the loose canvas and tie it along the boom with the reef points. The reef points only tidy up the canvas, they carry no load, so do not tie them with force.
Single-line reefing system
Some yachts have a reefing system where the whole operation is done with lines from the cockpit or with a winch handle at the boom. Convenient, because nobody has to go onto the coachroof. The principle is the same: ease the halyard, take in the reefing line, tension the halyard again. Systems differ in details between yachts, so once more: ask the owner at check-in, and ideally put in one practice reef on the first day in light wind.
The furling jib: the simplest sail reduction
The jib on charter yachts is almost always furled on the forestay. It is the fastest way to reduce sail: ease the jib sheet, pull the furling line and the sail rolls up on the stay. You can furl part of it, you can furl all of it. A partly rolled jib has a worse profile and pulls less, but in strong wind that is no problem, because you have excess power anyway.
One note: the furler tempts you to reef with it alone, because it is two seconds of work. And here the topic of balance comes in.
Balance: smaller main or smaller jib
A yacht under sail should carry slight weather helm, meaning it should gently head up into the wind on its own. That is safe, because a released helm turns the yacht into the wind and kills the power. The trouble starts when you reduce the sails unevenly.
- Furl too much jib and leave a full main: the yacht gets heavy weather helm, the tiller loads up, and the boat rounds up into the wind on every gust.
- Reef the main hard and leave a full jib: the yacht develops lee helm, bears away from the wind on its own and is hard to head up. That is the worse situation, because in a squall you want to be able to head up quickly and dump the power.
So reduce more or less proportionally. The typical order on a Masurian yacht: first the first reef in the main, then rolling in a third to half of the jib, then the second reef in the main and a deeper-furled jib. If the yacht still pulls the helm toward the wind, add a reef in the main. If it does not want to head up, furl in a bit of jib. You will find more on how to feel the yacht at the helm in our piece on sail trim for beginners.
How much wind, how much sail
Below is a rough-guide table for a typical charter sailboat with a crew of little to moderate experience. The scale itself and how it looks on a lake is covered separately in our article on the Beaufort scale on a lake.
| Wind | What you do with the sails |
|---|---|
| 1-3B, light and moderate | Full sails. A good moment to practise reefing calmly. |
| 4B, white caps on the waves | Beginner crew: first reef in the main, jib slightly rolled in. Experienced: full sails, but a reef on standby. |
| 5B, the wind clearly presses | Reef in the main plus a partly furled jib for everyone. Beginners are best off staying in port altogether. |
| 6B, strong wind | Second reef, jib deeply furled or put away completely. The water is for experienced crews only. |
| 7B and above, squalls | Sails down, engine on, course to port or to a sheltered spot. Nobody has anything to prove. |
Treat this as a starting point, not rigid law. No two yachts are alike, and no two crews either.
When to drop the sails and motor
There is a moment when reefing stops making sense. If the yacht lies over in the gusts even under shortened sail, the helm fights you and the crew is scared, then drop or furl everything and go on the engine. Bow into the wind and waves, calmly, to the nearest shelter. The engine on a Masurian sailboat is not a shame, it is safety equipment.
And the most important, Masurian matter: summer squalls come fast, often after a hot, sultry day. A black wall of cloud from the west is a signal to shorten sail now, not in fifteen minutes. History knows the finale of ignoring that signal, we described it in our piece on the white squall in Masuria. Check the forecast before every departure; how to do it like a sailor is covered in our guide to weather and safety in Masuria. If the forecast says above 5B and you are in your first or second season, stay in port. The lake will not run away.
Frequently asked questions
When should you reef the sails? The first time you think about it. Ideally back in port or on calm water, based on the forecast and what you see in the sky. A reef put in too early is easy to shake out; a reef put in during a squall is already a rescue operation.
Does reefing slow the yacht down? In strong wind, no. A yacht overloaded with canvas lies over on its side, drags the hull as a brake and wanders off course. A reefed one sails straighter and faster, and the crew sits in the cockpit instead of hanging off the rail.
What if I did not manage to reef before the squall? First kill the power: ease the sheets and head up into the wind. Furl the jib on the furler, because that is the fastest. Then start the engine, put the bow close to the wind line and only then calmly reef or drop the main. Do not try to reef with full power in the sails.
Is furling the jib alone enough instead of reefing the main? For the first reduction, often yes. But if you furl a lot of jib and leave a full main, the yacht will develop excessive weather helm and get heavy on the tiller. In stronger wind reef the main too, to keep the balance.
