Oyster 565 Gennaker

The Gennaker blends features of both Code 0 sails and asymmetric spinnakers. It’s typically designed with a flying shape and power positioned to bridge the gap between these two on the polar diagram.

 

 

Design & Construction

A wide range of fabrics are available from the highly durable woven polyester (dacron), through to single and double taffeta laminates. Dacron fabrics are generally used in a cross-cut construction giving good shape holding and great longevity.

For enhanced shape holding, weight saving and speed, a tri-radial construction utilising the warp orientated laminated fabrics is employed. Greater performance will be achieved with a Pentex laminate whilst Vectran/Dyneema will produce the best shape holding capability in panelled sails.

Membrane sails produce the ultimate in performance and shape holding capability. Each Membrane is designed bespoke to the yacht and customer needs. There are various yarn options that we use to create the sails using Kevlar, Carbon, Dyneema or Vectran to get the best longevity and durability.

Furling Genoa

Dolphin furling Genoas are based on the shapes we have evolved during countless hours in our research and testing
for racing Genoas. Subtle differences have been incorporated that are furling Genoa specific.

The luff entry has been given a more round user-friendly shape whilst the leach exit is shaped to help accommodate the UV strip that most furling Genoas have.

We would recommend the addition of a foam luff to help maintain a flat shape when partially
furled.

Description

The Gennaker blends features of both Code 0 sails and asymmetric spinnakers. It’s typically designed with a flying shape and power positioned to bridge the gap between these two on the polar diagram.

Gennakers can be used across a wide range of wind angles. When beam to broad reaching, the Gennaker experiences slightly less load than the Code 0, allowing it to be made from more typical downwind materials like nylon and polyester.

As a great alternative to an asymmetric spinnaker, Gennakers are easy to handle and offer impressive performance.
