Z42 Performance Racing and Cruising Sail Membranes
The Next Dimension in All-round Performance Sail Membranes.
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, and sailing style, as well as its 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.
Z42 Membrane Genoa, Z42 Membrane Jib and Z42 Membrane Mainsail
If you are after all the benefits of the Z72 structure with added abrasion resistance in a high-performance Genoa, Jib, or Mainsail for local club or offshore racing, look no further than our Z42 Membrane range.
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, Carbon, and other ultra-high-molecular-weight low-stretch fibres combined with ultralight wear-resistant cover materials that offer improved resistance to tears and abrasion and our ultra-flexible adhesives. The membranes are completed by lamination under high pressure to ensure a complete structural bond. The Z42 range uses the same process as the Z72 membrane with added abrasion resistance whilst offering an ultra-light sail.
While 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 Z42 membrane but want a lighter, moisture-resistant Mylar-based sail, consider the Z72 range. If you are looking for the ultimate in longevity, wear, and UV resistance, look at the Z09 range.
