Dacron Cross-Cut - Cruising Genoa

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.

DACRON

Dillons' cross-cut Dacron sails are for cruising sailors whose main concerns are price and longevity. 

Dacron cross-cut sails have all the panels parallel to each other and perpendicular to the leech.

Fabrics with their greatest strength in the fill direction are used to withstand the anticipated loading along the leech of the sail since the greatest loads in any sail are up and down the leech. 

Cruising sailors choose Dacron sails for their all-around strength and good value. 

When longevity is the main concern, Dacron is the cloth of choice as it is resistant to most types of wear that a sail experiences during its lifetime.

Dacron sails have a fair amount of UV resistance, they are virtually unaffected by bending and folding forces, and are resistant to chafe which is convenient when it comes to overlapping genoas.

Additional options, such as the UV-Protective luff and foot covers for furling headsails, can considerably prolong your sail's life.

The trade-off in choosing the longevity of Dacron is extended performance life.

While a Dacron sail will stay in one piece for many years, it starts losing its aerodynamic shape over time because polyester yarn is stretchy compared to high tech yarns like aramid and carbon fiber.

Extra Durability With Taffeta

While very strong,  Taffeta sails are made more durable with the addition of a finely woven polyester taffeta layer laminated to one or  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 

sails-1.jpg

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.

HeAD BOARDS

Figure-4-A-square-top-mainsail.png

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.
