For sailors, different conditions call for different techniques on the waters. As an actual or aspiring sailor, you do not want to find yourself in desperate situations before thinking of the possibilities open to you. Sailing with a jib, for example, makes sense for certain situations, and you need to be aware of the possibilities of sailing with just a jib. For starters, a jib isn’t as
effective as the mainsail when sailing from any point of sail. After some research into the topic, here’s some detail into whether you can sail with just a jib.
You can sail with a jib alone, depending on certain conditions. However, it is often advised against if you are not sailing on your own boat. There’s a need to realize that you must be willing to take risks in order to embark on this venture. Sailing successfully with just a jib will depend on certain conditions.
The argument on the safety and convenience of a jib didn’t just start today. Sailing with just the jib is an adventure convenient for moments when you want to take a short sail in the moderate wind for an hour or two. It is also a good alternative for high wind situations to reduce the sail area accordingly, especially when the mainsail has already made a double reefing. Although it is possible to sail with just the jib, there are many questions to answer and several boxes to tick before embarking on such adventures.
Efficiency and Performance Issues When Sailing With a Jib
Alone in High Wind
It’s been discovered over time that sailing in high wind speed is often more efficient when sailing with only the jib. While some boats are rigged to sail on the mainsail, some others are Genoa driven. Irrespective of how the boat is rigged, the truth remains that they are imbalanced when sailed on the main sail or Genoa only under high wind.
Most sailors discover that the weather helm tends to develop, especially when sailing under a higher wind speed of between 20 – 25 knots. You’ll find that the boat would become difficult to steer at such moments, making it uncomfortable for those on board. Even the most experienced sailors tend to set too much sail when sailing with only a main sail or a Genoa. Consequently, the boat easily loses balance, creating a weather helm.
On the other hand, the jib alone would be able to provide enough power to stand against high wind speed. While the boat would sail more efficiently with both the jib and the mainsail, you can opt for using only the jib in this condition if it’s more simple and convenient for you.
Managing a Lee Helm When Sailing With Only A Jib
One of the major issues that sailors tend to face while tack sailing is lee helm, which is a tendency to turn away from the wind. This is a different scenario from what you experience when you sail with jib and the mainsail. It is a clear reflection of the balance to expect from the job only when sailing.
If you sail constantly, you might have observed the considerable pressure experienced on the rudder, which disappears when the mainsail is raised. Typically, the mainsail balances the effects of the lee helm. However, if you decide to sail with the jib alone, then you can expect the boat to turn to the central pivot point as the wind fills the jib sail.
At this point, it becomes the duty of the helmsperson to apply a little windward pressure on the wheel, which is the opposite of the typical requirements in normal conditions. As the helmsperson, you have to return it at this point to close-hauled, which can be quite tricky when you are sailing with a jib alone.
Bearing this in mind, you can tell that it’s not a good idea to sail upwind with only a jib considering that the lee helm effect may happen just anywhere. Note, however, that apart from the difficulty to sail that comes with it, no damage would be caused.
Using a Jib Only To Sail Downwind
This is another aspect of sailing that newbies and prospective sailors are always asking questions about. When using only a jib to sail downwind, the wind’s consistency will get the sail to be filled. Sail boats are typically designed to perform best with a jib and a mainsail. However, if you are sailing downwind for long or get too lazy during a sail, then a jib alone can suffice as a useful alternative.
One advantage of sailing like this is that it eliminates accidental jibes since there isn’t a mainsail. However, most experts would advise that you maintain the tightness of the lazy sheet to prevent the jib from wrapping around the forestay.
Sailing a Jib Only – How to Manage Losing Momentum?
It is easy for the boat to lose momentum when the jib stalls. This is especially because of the helms person’s inability to continue in the proper angle of the wind’s direction when faced with such situations. The closer the helmsperson steers to the wind, the more you should expect the
boat to slow down. The best thing to do in this condition is to trim your jib sheet and adjust the boat so that the boat’s angle or jib can be corrected against the wind again. As you do this, the speed of the boat will gradually pick up.
Sailing With Just an Overlapping Genoa
A balance of pressure before and after the mast would typically make the boat to sail well. However, using a small jib can create a potential difficulty for you to sail to the wind’s direction. A large overlapping jib, on the other hand, can help you improve the condition of sailing. Such large jibs as a 150% Genoa are designed to have some of their surfaces after the mast, giving enough balance to the forces on the sail.
With this, you can expect the boat to sail relatively fairly when going windward. However, it’s important to mention that tacking with such a big sail creates more difficulty for sailors that might decide to tack in light air.
On the other hand, you’ll find that smaller sails would tack more easily in light air conditions as its design makes it snag on the rigging when the boat moves across the wind’s eye. So you can see that it is more suitable to use an overlapping sail when hit by a moderate wind then you are trying to sail upwind with a jib only.
If you are sailing upwind in a heavy wind condition, then perhaps it’s better to have two sails up for your boat to perform better. The only time you can use only s jib in s heavy wind situation is even when you are sailing downwind.
Adjusting Your Speed
Sometimes, the right thing to do to improve the comfort and motion of your boat is slowing down. Other times, adding speed and power would help improve your ride as you steer around the biggest waves. It takes skills to know when to apply which and this article includes enough information to get you through any situation. Note that there are times when you’ll need to rely on experimentation to get the right speed for a situation.
As explained, it is possible to sail with a jib only; however, it depends on several situations. Understanding the different sailing conditions and what suits all will help any sailor get through them.
