Headsail Furler

Sizing Guide & Selection Tool

How to Choose the Right Yacht Furling System

Matching your yacht to the correct headsail furler depends on your specific rigging dimensions, wire load limits, and cruising style.

Use our Quick Reference Chart below for an instant, at-a-glance guide to how our Australian-made models line up with standard rig dimensions and boat lengths.

To confirm the exact model for your vessel and go directly to its product page, use our Interactive Selector Tool below. Simply enter your rigging details, and the tool will instantly point you to the correct system so you can secure your unit from our upcoming production release.

Choosing the Right Reefit Furler

A sensible process to get it right

Headsail furlers are not a one‑size‑fits‑all product. Correct selection requires consideration of rig geometry, forestay specification, and the loads generated under sail.

With multiple components—including foils, joiners, connectors, bearings, and structural elements—each system must be matched carefully to the yacht to ensure reliable operation and long service life.

At its core, headsail furler selection is about managing load. Forestay length and diameter, pin size, sail area, and intended use all influence how loads are transferred through the system. An undersized unit may operate initially but suffer premature wear, deformation, or failure under sustained load. Conversely, an appropriately specified system will maintain smooth operation and structural integrity over time.

Each Reefit furling system is supplied as a complete assembly, with components engineered to work together under load and in harsh marine environments. Correct configuration ensures proper alignment, bearing performance, and even load distribution along the foil sections.

Our primary sizing reference point is the forestay pin size and forestay length, as it provides a reliable indication of the rig’s load capacity. From there, other factors—such as vessel size, sail plan, and usage profile—are considered to confirm the correct system selection.

The process below outlines how we recommend approaching this decision.

Step 1 — Understand Your Boat and How It’s Used

Boat length alone doesn’t tell the full story. Two boats of the same length can place very different loads on a furling system. Before choosing a Reefit furler, take the time to understand:

  • Boat length and displacement

  • Rig type and mast height

  • Forestay size and construction

  • Typical sailing conditions

  • How the boat is actually used (coastal, offshore, short‑handed, extended cruising)

Being honest about how the boat is sailed helps ensure the system is properly matched to real working loads, not just brochure specifications.

Step 2 — Get Advice from a Rigger or Sailmaker

This step is strongly recommended.

A qualified rigger or sailmaker brings practical experience that’s hard to replace. They can:

  • Confirm rig suitability

  • Take accurate measurements

  • Check load paths and clearances

  • Advise you on sail compatibility

  • Install the system correctly

They also understand how furlers interact with sails, halyards, and rig tuning — things that aren’t always obvious from specifications alone. Involving a professional early often saves time, cost, and frustration later.

Step 3 — Assess Your Rig, Forestay & Measure

A furling system is only as good as the rig it’s attached to.

Before selecting a system, the existing forestay and rig setup should be assessed. This includes:

  • Condition, age of the forestay, and size of the forestay pin

  • Forestay length and termination type

  • Clearance at the stem fitting and mast

  • Alignment of the stay under load

In some cases, replacing or upgrading the forestay is part of doing the job properly. This isn’t a downside — it’s good practice and helps ensure long‑term reliability.

Step 4 — Match the Correct Reefit System

Once the boat and rig have been properly assessed, the correct Reefit system can be selected based on:

  • Load requirements

  • Forestay & Clevis Pin size

  • Boat size and displacement

  • Intended sailing conditions

Reefit systems are designed as complete control systems, not just hardware. Installing the right system, correctly, delivers smooth operation, long service life, and reliable support over time.

If there’s any uncertainty, ask — it’s always better to confirm than guess.
