Furling mainsails have become increasingly popular among sailors due to their convenience and ease of use. They allow sailors to quickly and easily deploy or stow the mainsail without leaving the cockpit, which can be particularly appealing for shorthanded crews or those with limited mobility. While there are many advantages to furling mainsails, there are also several disadvantages that should be considered before deciding whether to use one.
Furling mainsails have reduced sail shape
Furling mainsails are designed to be rolled up around a stay or mast and are flatter and less contoured than traditional mainsails, limiting their ability to generate lift and power in certain wind conditions. In light wind conditions, a furling mainsail may struggle to generate the necessary power to keep the boat moving at an optimal speed.
The furling mainsail’s reduced sail shape can also make it more difficult to control the boat. This can be particularly problematic in heavy weather, where sailors need to be able to reef their sails quickly and efficiently to maintain control and prevent accidents. Overall, while furling mainsails offer some convenience, their reduced shape is a significant drawback that sailors should carefully consider when choosing a sail system for their boat.
Common Furling Mainsail Problems
Difficulty in reefing with furling mainsails
One potential disadvantage of furling mainsails is the difficulty of reefing, which can be especially challenging in heavy weather. Reefing refers to the process of reducing the sail area in response to increasing wind speeds, which helps to maintain control of the boat and prevent damage to the sail or rigging. However, furling systems can make this process more complicated, as the sail is rolled up around the mast rather than being lowered and tied off. This can make it difficult to achieve the desired level of reefing and may require more time and effort to get it right.
Aside from the difficulty of reefing itself, the process can also make sailing more dangerous and stressful. For example, if the sail is not reefed enough, the boat may become overpowered and difficult to control, increasing the risk of capsizing or other accidents. On the other hand, if the sail is reefed too much, the boat may lose speed and maneuverability, making it difficult to sail effectively. Other potential difficulties with reefing a furling mainsail include:
- Increased complexity of the system, which can make it harder to understand and troubleshoot
- Limited visibility of the sail when it is rolled up can make it harder to judge the appropriate level of reefing.
- There is a risk of jams or other malfunctions in the furling system, which can make it impossible to reef the sail when needed.
Overall, while furling mainsails can offer convenience and ease of use in certain situations, they may not be the best choice for all sailors or sailing conditions due to the associated challenges and risks.
Added weight aloft of furling mainsails
The added weight aloft caused by the furling system can significantly impact the boat’s overall stability. When a boat is heeled over in the wind, the weight distribution of the boat changes, and the center of gravity shifts towards the side that’s heeled over. This means that any extra weight high up on the mast can affect the stability of the boat much more than the weight lower down.
The additional weight aloft can also make it more challenging to right the boat in the event of a capsize. If it ends up upside down in the water, the added weight on the mast can make it harder for the crew to right the boat by pushing it down on the centerboard or keel. This can be particularly problematic in heavy weather conditions when the crew is already struggling to stay afloat and manage the boat.
Increased complexity of the furling system
Furling mainsail systems consist of several components: a furling drum, a forestay, a halyard, and a control line. This complexity can make the system harder to maintain, and if not cared for appropriately, it can malfunction. As a result, sailors must regularly inspect and maintain their furling systems to avoid costly repairs and failures at sea.
Repairing a furling mainsail can be both time-consuming and expensive. If the system breaks down during a voyage, repairing it may require the boat to be brought ashore and taken out of the water. This can lead to additional costs and time-consuming repairs. Furthermore, furling systems require specific knowledge and skill to repair, which may be beyond the expertise of many sailors. This means that sailors may have to seek out specialized repair services, further adding to the overall cost of the system.

The higher cost of a furling system
The cost is one of the main disadvantages of furling mainsail systems, which may deter some sailors from investing in this technology. Here are some reasons why furling systems can be more expensive:
- Initial cost – Furling systems are generally more expensive than traditional mainsails, as they require more hardware and engineering to function properly. This cost can be a significant barrier for new sailors or those on a tight budget.
- Installation and maintenance – Installing a furling mainsail system can be a complex and time-consuming process that requires professional installation and ongoing maintenance to ensure proper function, adding to the overall cost of the system.
- Repair costs – If something goes wrong with your boat’s furling mainsails, replacement parts, and labor can be expensive, and most repairs need a skilled technician to figure out what’s wrong and fix it.
- Upgrades – As technology evolves, newer and more advanced furling systems may become available. Upgrading to these systems can be costly, especially if they require a different size or type of sail.
Conclusion
While furling mainsails offer convenience and ease of use, they also have several disadvantages that sailors should carefully consider. These include reduced sail shape, difficulty reefing, added weight aloft, increased complexity, and potential high expense. Sailors can mitigate some of these disadvantages by choosing the right system for their boat and sailing conditions, and by properly maintaining their furling system.
