Cruising Genoa- Double Taffeta
Dear viewer, having been in the Sailing Industry for 27 years, I work with Doyle, North and UK Sail Lofts internationally, as well as a few local lofts scattered around the world.
Purchasing a specific sail for your boat is a personal transaction and you need to feel confident with the advice you you are receiving. I always work closely with my client and the company who builds the sail.
The expertise and services I personally offer are the re-cutting, re-designing, measuring and installation of a new or existing sail or suit of sails. If there are any furling, reefing or rigging faults, these I normally pick up when inspecting and measuring and will advise of any upgrades or changes necessary or available.
Grand-Prix / Racing Sails
These I normally refer to Mark Plough who owned a UK Sail Loft and now has 4 Sail Lofts on the East Coast (USA) including a Doyle Sail Loft in New York. His Name, reputation and expertise in this field is unsurpassed. He is also a really nice man who runs an awesome business and always has time for interesting projects.
For hand leather finishing, or a molded full batten main that slides on a double track system for a 110 foot mast you are welcome to speak with me regarding your custom design requirements.
Double Taffeta- Cruising Genoa
For cruising boats 40-100 feet
Double-Taffeta cruising sails are a great option instead of heavy, multi-ply Dacron or radially-paneled sails. Double-Taffeta sails are made with continuous load-path yarns fused between two layers of film.
The exposed side of the film is covered with a finely woven polyester taffeta – creating a five-layer sandwich
Double Taffeta sails are made with a grid of continuous carbon load path yarns running unbroken between the three corners of the sail; those yarns are laminated between two layers of 3D-shaped film.
In the construction process, the yarns are laid dry–without glue–to reduce weight and to prevent the carbon yarns from becoming brittle.
The mylar films are tacky on the inside from the co-polymer coating; this holds the yarns and films in place until the final lamination has been completed.
The five layers (taffeta, film, load-path yarns, second film layer, taffeta) are dropped into a variable geometry thermo- form in which the sail is heated and UV-bonded under vacuum pressure to become a one-piece finished membrane.
Not coating the yarns with glue makes for lighter (by 15-30%), more flexible, and more durable sails, which makes happier foredeck teams and happier owners who are not replacing their misshaped and broken sails as often.
Yes, there are seams in a double taffeta sail, but they are there simply to shape the film layers.
Unlike most high-tech sails in which structural yarns only run the width of an individual panel, a double taffeta sail’s continuous yarns eliminate seam loads, load-induced seam distortion, wrinkles, or worse yet, seam failure. These sails are smooth and wrinkle free.
Extra Durability With Taffeta
While very strong, Titanium Double-Taffeta sails are made more durable with the addition of a finely woven polyester taffeta layer laminated to both sides. The taffeta layers don't add strength to the sail, but they protect the film layer from abrasion, which is a great benefit for cruising sailors. Taffeta comes in white or grey.

Foil Shaping / sail fabrication
Once the size and boat weight has been calculated the foils for a given wind condition is then formulated and integrated into the mold for the sail.
Down wind sails have a different shape to up wind etc.
Batten designs and pocket forms to fit existing hardware is incorporated into the lamination and fabrication of the sail.
Stitching sails and finishing
All sail are stitched at some point or in their entirety. Keeping ones machines well tuned is a function of the loft machine mechanic. As this is a dwindling business there are fewer and fewer machine mechanics. So much so that the manufacturers of the sewing machines do not have service departments or personnel to tune the machines. I have had to learn the machine I have owned and operated in order to keep staff working. this normally means 1-2 hours ever night checking the machines after staff have left.
The headboard is one of the most important parts of your sail.
If the angle of attack for the halyard is not set correctly you main will loose its shape and function incorrectly.
I like to inspect the mast head, stand off and shiv set up when measuring for the sail. Maximizing the efficiency of a sail is paramount to the functionality a sail offers.

Having owned and worked in leading American Marine companies until 2015 Dillon Oberholzer sold his businesses and moved from the USA to Guatemala to further his work in Marine Bacteria Remediation.
This in turn led to the development of SJC where his skills have been put to the test in incorporating modern state of the art manufacturing processes integrated with local hand woven products, all protected with "BMS" Bio -Static, Anti Microbial, water resistant finishes.
Our CAD and technical abilities allow our clients to order products online within fabrication tolerances of 1 mm per 10 meters of final product manufacture.
