Cruising Spinnaker
The Cruising Spinnaker is smaller than a full size spinnaker, but larger than a genoa. This very light and performance-minded sail may be flown with or without a spinnaker pole. It is an excellent short-handed light air flyer. The cruising Spinnaker should be used with a Chute Scoop for added handling ability .
Asymmetrical
The Cruising Asymmetrical, as we've come to know it, is really a symmetrical spinnaker with one leech/luff cut about three feet shorter. The true asymmetrical which we see on the Cup boats, the newer J class boats, and the Melges 24 is a completely different sail. With a defined luff/leech, the draft is forward of center and the overall size is "huge." Of course it can be size altered for your specific purpose. They are new and exciting and offer a new experience to your sailing.
Tri-Radial
A long time "all-purpose" industry standard has been the Tri-Radial Spinnaker. It is not as popular today as Warp Cut tri-Radial, but it is still an excellent sail for the right boat and purpose. The Tri-Radial is priced slightly less than the Warp True Tri-Radial, with optional weights and fabrics.
Warp True Tri Radial
This is the strongest and fastest spinnaker available today. It is called Warp True Tri-Radial because the fabric is laid out in the panel direction aimed along the load map of the sail. Maximum strength is absorbed from the fabric so that the sail is as strong as it can be. It shows its true value on larger boats where strength can really be tested. The Warp True Tri-Radial can be made from a variety of weights and fabrics.
Cross-Cut
The Original Cross Cut has been a long time industry standard. Considered conservative by today's designs, it is still very popular among cruisers. Generally made of Dacron, the Cross Cut shapes very well during construction and with proper cloth selection will stand up well against more elaborate layouts. Best of all, because of its uncomplicated design, it is the least expensive. Hank on to the forestay or add leech and foot covers for the roller system.
Tri-Radial
Called Tri-Radial because of panels radiating from all three corners of the sail. It is designed to minimize stretch and reduce overall weight. Generally made from Dacron and/or Mylar Composite materials, this basic layout is today's leading standard. Add foot and leech covers for the roller system.
Max-Plus Tri-Radial
Max-Plus is just another name used for what sailmakers call a Tri-Radial. Panels radiate from all three corners and continue through the sail arranged to follow the load map of the sail. Designed to align the threat line in the maximum load direction, the Max-Plus can be built from several types of composites including Kevlar-Mylar, Technora Black, Spectra, etc. Weights may be mixed to produce a "step-up" construction to further reduce overall weight. With this design, Stretch is kept to near zero and weight to an absolute minimum. Can be "pricey," but very fast.
Full-Length Battened Main
This mainsail today is, without a doubt, the most popular among cruisers and many racers. The full battens keep the sail quiet when luffing and best of all, help maintain a smooth, fair shape. With the aid of full-length battens, a new sail may be made larger for that little extra performance you have been looking for. Install a Dutchman system or Lazy Jacks and you have a sail that even puts itself to bed.
Cross-Cut
The Cross-Cut Main still remains the industry standard. It makes a great cruising sail that lasts for years and is quite popular in many racing circles. Many styles of fabric can be used to accomodate any aspect ratio rig.
Full Batten Performance Main
The Full Batten Performance Main is one usually built of Dacron. Full battens are used for the top two or three depending on the flexibility of the rig. The lower batten is conventional, but extra long. This sail is quite durable, very competitive, and much less expensive than the aramids.
Tri-Radial Racing
This sail is bred for pure speed. It is built light and strong using only the latest materials such as Kevlar, Mylar, Technora Black and Spectra. This cut generally incorporates two full battens at the top and two extra long lower battens. Unfortunately, after two seasons of hard use, you will probably need a new sail. However, if you are looking for speed or that high-tech look, Tri-Radial is an excellent design.
