As a supplier of catamaran sailboats, I often get asked about the types of sails used on these vessels. Catamarans are unique in their design, with two hulls providing stability and speed. The choice of sails can significantly impact a catamaran's performance, comfort, and overall sailing experience. In this blog, I'll explore the different types of sails commonly used on catamaran sailboats.
Bermuda Rig Sails
The Bermuda rig, also known as the Marconi rig, is one of the most popular sail setups for catamarans. It consists of a single mast with a triangular mainsail and a headsail, typically a jib or a genoa. The mainsail is attached to the mast and boom, while the headsail is attached to the forestay.
One of the main advantages of the Bermuda rig is its simplicity and versatility. It's easy to handle, making it suitable for both novice and experienced sailors. The triangular shape of the sails allows for efficient sailing upwind, as the wind can be directed more effectively to generate forward motion. This rig is also highly adjustable, with the ability to reef the sails (reduce their area) in strong winds, ensuring safety and control.
For catamarans, the Bermuda rig provides a good balance between speed and stability. The large mainsail can capture a significant amount of wind, while the headsail helps to balance the forces on the boat. This setup is ideal for cruising and racing, as it allows for quick maneuvers and efficient sailing in various wind conditions.

Gaff Rig Sails
The gaff rig is a traditional sail setup that has been used for centuries. It consists of a mast with a gaff (a spar that extends diagonally from the masthead) and a four-sided mainsail. The gaff rig also typically includes a jib or a staysail.
One of the characteristics of the gaff rig is its distinctive shape, which gives the sailboat a classic and elegant appearance. The gaff sail has a larger area at the top, which can be beneficial in light winds, as it can capture more wind at higher altitudes. This rig is also known for its smooth and stable sailing performance, making it a popular choice for cruising catamarans.
However, the gaff rig requires more complex handling compared to the Bermuda rig. The gaff and the additional spars add weight and complexity to the sail setup, which can make it more challenging to reef and adjust the sails. Despite these challenges, many sailors appreciate the traditional charm and unique sailing experience offered by the gaff rig.
Junk Rig Sails
The junk rig is a unique sail setup that originated in China. It consists of a series of horizontal battens attached to a vertical mast, creating a rectangular sail shape. The junk rig is known for its simplicity and efficiency, as it can be easily reefed and adjusted.
One of the main advantages of the junk rig is its ease of handling. The horizontal battens divide the sail into smaller sections, which can be individually reefed or adjusted. This makes it possible to reduce the sail area quickly and easily in strong winds, without the need for complex knotting or tying. The junk rig also has a relatively low center of effort, which can improve the stability of the catamaran.
In addition, the junk rig is considered to be more eco-friendly compared to other sail setups. The simple design and efficient use of materials make it a sustainable choice for sailing. If you're interested in an Eco-friendly Sailboat, our catamarans with the junk rig might be the perfect option for you.
Asymmetrical Spinnaker
The asymmetrical spinnaker is a large, lightweight sail that is used for downwind sailing. It has a triangular shape with a curved leech and a flat luff. The asymmetrical spinnaker is designed to be flown from a sprit or a bowsprit, which extends the sail forward of the bow.
One of the main advantages of the asymmetrical spinnaker is its ability to generate high speeds downwind. The large sail area can capture a significant amount of wind, allowing the catamaran to reach impressive speeds. The asymmetrical shape also makes it easier to handle compared to the traditional symmetrical spinnaker, as it doesn't require a pole to hold the sail out.
However, the asymmetrical spinnaker requires careful handling and coordination. It needs to be set and trimmed correctly to ensure optimal performance. In addition, it's important to have the right wind conditions and sailing skills to use the spinnaker safely.
Code Sails
Code sails are a type of specialized sail that is designed for specific wind angles and conditions. They are typically used in racing catamarans, but can also be found on some cruising vessels. Code sails come in different numbers, such as Code 0, Code 1, Code 2, etc., each with a specific design and purpose.
Code 0 is a light-air reaching sail that is used in very light winds. It has a large area and a flat shape, which allows it to capture as much wind as possible. Code 1 is a more powerful reaching sail that is used in moderate winds. It has a deeper shape and more camber, which provides more lift and speed. Code 2 and higher numbers are designed for stronger winds and broader angles.
Code sails are highly adjustable and can be customized to suit the specific needs of the catamaran and the sailing conditions. They require advanced sailing skills and knowledge to use effectively, but they can significantly improve the performance of the boat in certain situations.
Choosing the Right Sails for Your Catamaran
When choosing the sails for your catamaran, there are several factors to consider. The type of sailing you plan to do, the wind conditions in your area, and your level of sailing experience are all important considerations.
If you're a novice sailor or plan to do mostly cruising, a simple and easy-to-handle sail setup like the Bermuda rig might be the best choice. It provides a good balance between performance and ease of use. On the other hand, if you're an experienced sailor or interested in racing, you might want to consider more specialized sails like the asymmetrical spinnaker or code sails.
In addition, the size and design of your catamaran can also affect the choice of sails. Larger catamarans may require larger sails to generate enough power, while smaller catamarans may be more suited to lighter and more maneuverable sails.
