Z09 Performance Cruising Sails

The Next Dimension in Durability and All-round Performance Sails.

Zeptyr Membranes represent the best balance of performance and value for every yacht wanting to increase performance. We provide the most suitable fibre and cover combination to suit your application and budget. Yachts with Zeptyr Membrane inventories are regularly on the podium or cruising the world. Our sail Membranes perform on Yachts of all sizes, from 50-foot grand prix racers to the smallest club racers.

Each Zeptyr Membrane is designed and engineered specifically for you. We consider your yacht’s specifications, typical wind ranges, sailing style, and intended locations to create the very best sail for any yacht of any size.

For the very best in durability and performance, a Zeptyr Membrane is an excellent choice for your Yacht.

Z09 Membrane Genoa, Z09 Membrane Jib and Z09 Membrane Mainsail

The Zeptyr Z09 range is the ultimate in performance cruising sails when planning to venture beyond your local waters. The Z09 finish has been designed to endure the elements and deliver many miles of performance sailing. This is the sail for those who want to travel the world with confidence in their sails.

If you want the benefits of the Z72 structure with added abrasion resistance, consider our Z09 Membrane range. It offers the ultimate in UV resistance in a high-performance Genoa, Jib, or Mainsail for performance cruising.

The Zeptyr Advantage

The main difference between a Zeptyr Membrane and off-the-shelf fabrics is that we control the fibre density, placement, and orientation throughout the sail. This saves significant weight and locks the sail in an optimised shape.

We use high-tech fibres like Twaron, Dyneema, and Carbon. These ultra-high molecular weight, low-stretch fibres are combined with wear-resistant, enhanced UV protection cover materials for added durability. This combination offers improved resistance to tears and abrasion. Our ultra-flexible adhesives complement these features. The membranes are laminated under high pressure to ensure a complete structural bond.

The Z09 range uses the same process as the Z72 membrane, with added abrasion resistance. Some membrane manufacturers lay their cloth in flat panels and shape the edges to create the 3D shape. As a result, they do not offer ‘true continuous fibre’ solutions. At Zeptyr, we lay our fibres directly onto the pre-shaped sail mould, ensuring a genuinely smooth aerodynamic profile.

If you want all the benefits of the Z09 membrane but with a lighter, moisture-resistant Mylar-based sail, the Z72 range is the answer. If you want a lighter sail and are willing to sacrifice some wear resistance, consider the Z42 range.
