Electric furler

What is an electric furler, and how does it function? 

An electric furler is a motorized system that automates the furling and unfurling of sails, reducing manual effort and improving control. It consists of a powered motor integrated with a drum or mandrel, rotating to roll the sail around a torsional cable or forestay. Activation is managed via a switch or remote control, allowing for precise sail deployment and retrieval, particularly useful for short-handed or performance-oriented sailing. 

What are the advantages of electric furlers over manual furlers

Electric furlers provide ease of use for older or short-handed crews. With an electric furler attached to the stay you can hoist it into position in the comfort of a marina leaving it furled and ready for use. This can be done at the start of a day's cruise and left in for the whole day being furled/unfurled as necessary in a matter of minutes.

Can an existing manual furler be upgraded to an electric system? 

Many existing manual furlers can be converted to electric operation, depending on their design and compatibility with motorized systems. Some manufacturers offer retrofit kits, but installation may require additional structural reinforcement and electrical modifications. Consulting with a rigging specialist ensures a seamless integration tailored to the yacht’s specific requirements. 

Is it easy to set up electric furlers and convert from a manual furler?

Some brands, like the premium Bamar BWSE furlers, will require a permanent installation into a customized bowsprit. Others, like Profurl NEXe and Facnor FXe are designed to be very easy to mount and dismount. They both have snap shackles to connect the drum to the bowsprit with quick release waterproof connectors which allow the unit to be removed from the foredeck when not in use. The only permanent installation is the power socket close to the bow. You can use your existing swivel and just change out for an electric drum. 

Can an electric furler be used for different types of sails? 

Electric furlers are commonly used for headsails, such as genoas, jibs, and flying sails (code sails, gennakers, and asymmetric spinnakers). Some systems are designed for structural forestays, while others work with torsional cables to handle free-flying sails. The choice of furler depends on sail type, size, and the yacht’s specific rigging configuration. 

Are these electric furlers made for Code zero or asymmetric sails?

Electric furlers are suitable for both - code zero and asymmetric sails using an adapter to convert from bottom up furling to top down furling. Electric furlers can be relatively slow compared to manual furlers and therefore not ideally suited for top down furling, where speed is very important to achieve a good furl. Primarily, these electric furlers are designed for Code zero.

Are electric furlers compatible with all yachts? 

Electric furlers are available in various sizes and power ratings to accommodate a broad range of yachts. However, compatibility is influenced by the yacht’s sail plan, electrical system, and rigging setup. Larger yachts with high loads may require more powerful furling motors and reinforced structural mounting. Proper selection ensures optimal performance and reliability. 

How is an electric furler powered, and what are the electrical considerations? 

Electric furlers typically operate on the yacht’s 12V or 24V electrical system. A dedicated power supply, adequate battery capacity, and appropriate wiring are essential to ensure consistent operation. Long-range cruisers and offshore sailors should factor in energy consumption to maintain system reliability, particularly when sailing in remote areas with limited charging capabilities. 

What safety features are integrated into electric furlers? 

Most electric furlers incorporate overload protection, emergency manual operation, and torque-limiting mechanisms to prevent excessive strain on the system. Some models include load sensors to detect resistance and automatically adjust furling force. Proper installation and adherence to recommended load limits further enhance operational safety and longevity. 

What maintenance does an electric furler require? 

Regular maintenance involves rinsing components with fresh water to prevent salt and debris buildup, inspecting electrical connections for corrosion, and checking mechanical parts for wear. Some furlers require periodic lubrication of bearings and moving elements. Ensuring proper sail tension and handling also reduces unnecessary stress on the system, preserving performance and longevity. 

How do electric furlers perform in strong winds and heavy loads? 

Electric furlers are engineered to handle significant sail loads in demanding conditions. Advanced models incorporate torque control and gradual start functions to prevent sudden loading, ensuring smooth and controlled furling. However, proper sail management practices—such as easing halyard tension and controlling furling speed—are essential to prevent excessive loads that could compromise the system. 

Are these electric furlers waterproof?

Yes, these electric furling units are completely waterproof and particular attention has been paid to the electrical connections to ensure they are waterproof to withstand the harsh conditions that are experienced on the bow of all sailing yachts.

What are the main features of electric furlers to look out in terms of performance?

The choose the right electric furler you need to know the SWL (Safe Working Load) for your boat. Once you know the correct SWL, the speed (in RPM) and the available power of the electric furler will be the key attributes to compare.

Key factors to be considered when selecting an electric furler

Selecting an electric furler requires evaluating sail size, type, load capacity, power requirements, and installation constraints. Other considerations include system weight, integration with existing rigging, and control options (wired or wireless). Long-term support, spare parts availability, and reliability in offshore conditions should also influence the decision-making process. Electric furlers for code zero or asymmetric sails are designed to improve handling, comfort and safety onboard with easy installation and low maintenance in a compact unit. We offer electric furlers from the leading furling brands, including Bamar, Facnor and Profurl.
