Genoa & Jib Furlers

By MAURIPRO Rigging Specialists · Updated March 2026

Genoa & jib furlers represent one of the most critical sail handling systems aboard modern cruising and racing yachts, enabling precise headsail control across diverse weather conditions. These sophisticated mechanisms combine engineered foil extrusions with precision-machined bearings and drum assemblies to deliver reliable, long-term performance under extreme loads. The technical excellence lies in the seamless integration of structural integrity with operational smoothness—essential for both coastal cruising and offshore passages.

At MAURIPRO, we specialize in premium Selden Furlex systems, including their revolutionary electric furlers and conversion kits that transform manual systems into push-button convenience. Our extensive inventory features the Furlex 304E electric series with varying stay length capacities, alongside comprehensive conversion solutions for upgrading existing 400 and 404 series installations. Whether you're retrofitting a classic yacht or outfitting a new build, our technical expertise ensures optimal furler selection based on your vessel's specific requirements, sail inventory, and operational profile.

How to Choose the Right Genoa & Jib Furlers

Boat Size and Stay Length Compatibility

The maximum stay length capacity directly determines furler compatibility with your vessel. Selden's Furlex 304E series accommodates stays ranging from 50 feet to 65 feet, making them suitable for mid-size cruising yachts and performance boats. The 50-foot maximum variants work effectively on vessels between 35-40 feet, while the 65-foot capacity models handle larger cruisers and racing yachts up to 50-55 feet overall length.

Stay diameter compatibility requires precise matching between the furler's foil extrusion and your existing rigging wire. The conversion kits offered by MAURIPRO accommodate both 12mm and 14mm wire configurations, with some models providing dual compatibility. Undersized furlers will experience premature bearing wear and potential structural failure under load, while oversized units create unnecessary windage and weight aloft.

Load Ratings and Structural Requirements

Furler load capacity must exceed your headsail's working loads by a significant safety margin. The Selden Furlex 400 series handles moderate cruising loads with wire sizes up to 14mm, suitable for working jibs and smaller genoas. The 404 series provides increased load capacity for larger overlapping genoas and heavy weather applications, incorporating reinforced bearing assemblies and upgraded swivel mechanisms.

Electric conversion systems like the 304E series integrate motor assemblies rated for continuous duty cycles under typical sailing loads. These units feature thermal protection and current limiting to prevent motor damage during high-load furling operations. The electrical systems require 12V DC power with current draws typically ranging from 15-25 amps during active furling cycles.

Manual vs Electric Operation

Electric furlers eliminate the physical effort required for large headsail management, particularly beneficial for shorthanded sailing or when handling oversized genoas. The Selden Furlex 304E systems provide remote operation capability with integrated safety features including automatic stall protection and manual override functionality. Electric units maintain consistent furling tension regardless of wind conditions, reducing sail distortion and improving longevity.

Conversion kits allow upgrading existing manual furlers to electric operation while retaining the proven mechanical components. The 400 to 400E and 404 to 404E conversion systems preserve your current foil and bearing assemblies while adding motor drive capability. These conversions typically require 6-8 hours of installation time and maintain full manual backup operation in case of electrical system failure.

Foil Design and Sail Compatibility

The extruded aluminum foil profile determines both aerodynamic efficiency and sail attachment methods. Selden furlers utilize precision-extruded foils with integrated sail tracks that accommodate standard bolt rope or tape-drive luff attachments. The foil's cross-sectional shape affects upwind performance, with streamlined profiles reducing drag while maintaining adequate structural stiffness for load transfer.

Bearing configuration within the furler directly impacts longevity and operating smoothness. Top-quality units incorporate sealed ball bearings or bronze bushings with scheduled lubrication requirements. The swivel mechanism must handle both rotational loads during furling operations and static tension loads when sailing, requiring robust construction with corrosion-resistant materials throughout the load path.

Installation and Rigging Integration

Furler installation requires precise alignment between the tack attachment point and the masthead connection to prevent binding during rotation. The drum assembly positioning affects furling line lead angles, with optimal installations maintaining 90-degree approaches to the cockpit winches. Existing chainplate and bow fitting modifications may be necessary to achieve proper geometric relationships.

Wire termination methods must match the furler's connection hardware, with most Selden systems accepting standard swaged or mechanical terminals. The conversion kits available through MAURIPRO include all necessary hardware for wire attachment and electrical connections where applicable. Professional installation ensures proper torque specifications and electrical integration with existing boat systems, particularly for electric furler variants requiring dedicated circuit protection and control panel integration.

Frequently Asked Questions

What's the difference between manual and electric furlers, and when should I choose electric?

Manual furlers require physical effort to furl and unfurl sails using winches or direct pulling, while electric furlers like the Selden Furlex 304E use motors for effortless operation. Electric furlers are ideal for larger boats (typically 40+ feet), short-handed sailing, or when crew strength is limited. They're particularly valuable in heavy weather when furling large genoas becomes physically demanding. MAURIPRO carries complete Selden electric furler systems with various stay length capacities to match your boat size.

Can I convert my existing manual furler to electric, and what's involved?

Yes, many manual furlers can be converted to electric operation using conversion kits. MAURIPRO stocks Selden Furlex conversion kits that upgrade 400 and 404 series furlers to their electric 'e' variants. These kits include the electric drive unit, wiring harness, and control systems needed for the conversion. The process typically requires removing the existing drum assembly and installing the new electric components, which can often be done without removing the entire forestay.

How do I determine the correct wire size (12mm vs 14mm) for my furler system?

Wire diameter depends on your boat's displacement, sail area, and existing rigging specifications. The 12mm wire is typically used on boats up to about 45 feet, while 14mm wire suits larger vessels with higher loads. Check your current forestay wire diameter first, as it's often best to match existing rigging. MAURIPRO offers Selden conversion kits in both 12mm and 14mm options, and some kits accommodate both sizes for maximum flexibility during installation.

What stay length capacity should I choose for my boat?

Stay length refers to the maximum forestay length the furler can accommodate, measured from the deck to the masthead. Measure your actual forestay length and choose a furler with capacity that exceeds this measurement by at least 10%. MAURIPRO's Selden Furlex 304E electric furlers are available with stay capacities ranging from 50 feet to 65 feet. Choosing the right capacity ensures proper drum sizing and adequate foil length for your headsail.

What maintenance do electric furlers require compared to manual systems?

Electric furlers require standard mechanical maintenance like greasing bearings and checking fasteners, plus electrical system care including motor servicing and wiring inspection. The electric motor should be inspected annually and may need brush replacement every few years depending on usage. Battery connections must be kept clean and tight, and the control unit should be protected from moisture. MAURIPRO recommends following Selden's maintenance schedules, which typically involve more frequent attention to electrical components than purely mechanical manual systems.
