Genoa Selection Guide

At Dolphin our philosophy is to apply the same attention to detail no matter how large or small the boat, whether racing or cruising. We help guide our customers through the sail selection process to ensure that they have the correct sail option to suit their sailing needs and expectations.

Where possible we will measure the boat’s rig, set-up characteristics and discuss with you any personal preferences. Our experience with building racing sails enables us to bring a wide based knowledge to the design and construction of your cruising sails. This experience is invaluable for the production of sails with excellent shape holding, sails that help you to get to your destination as quickly as possible. Boatspeed is important. How often do we hear “I’m not worried about boatspeed”, but when we actually get out there we tweak and trim to try to get past the boat in front? We can’t help ourselves!

Of equal importance of course is the ease of handling and use of a sail. Dolphin take care to ensure both the sail handling and sail handling systems make your cruising as pleasurable an experience as possible.

Furling Genoas

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.

Sail Design & Construction

Cross cut

Tri radial

Membrane

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.

Sail Specification – Cruise

Tri Radial

Dolphin tri-radial furling Genoas offer the lowest stretch and ultimate shape holding capability for the cruising sailor seeking the highest performance. The complex panel construction is finely tuned to match the catinery load paths in the sail. A range of fabrics are available from woven polyesters to taffeta laminates in polyester or Pentex through to Carbon and Dyneema.

Cross Cut

Dolphin cross cut furling genoas utilise the highest specification dacron fabric. This provides high strength, low stretch, durability and longevity, the prerequisites for any cruising sail. Whilst cross cut, the panels are orientated in a ‘rocked’ arrangement that aligns the stronger fill orientated fibres carefully with the catinery loads in the sail.

UV Sun Guard

Our UV sun guards are fitted in Odyssey as standard with the option of a WeatherMax 80 fabric upgrade, this depends on your application and also weather the UV guard needs to match in with the cover colour scheme on your boat. If you are planning on sailing abroad in high UV areas then the weathermax fabric is a must.

The UV Sun guard is stitched to the leech and foot of the headsail. The side that the UV is fitted depends on which way your furling gear turns when being furled away. We recommend that if you are not wanting to fit a UV guard then you either purchase a Genoa Sock cover or take your headsail down when leaving the boat for long periods of time.

Foam Luff

Foam luff helps with retention of shape when partially furled. The foam luff inserts work by helping to suck out the unwanted sail shape when sailing with the sail partially furled. It reduces the unsightly creases that form from the head and tack of the headsail and create a smoother entry, in turn enhancing the sail shape and performance whilst sailing with the genoa partly furled.
