ISTEC’s redeveloped Parasailor is a breakthrough in sail design and will set a new standard in sailing.
The special features of the Parasailor mean that it is a replacement for both traditional spinnakers and also gennakers.
The sail is divided into an upper and a lower section. This allows a profiled, three-dimensional, pressure–filled wing to be positioned into the air current of the opening between the two sections. This wing was developed in a similar way to a paraglider or kite surfer ram air kite and it creates considerable forward motion and lift. This decreases the horizontal force on the spinnaker head and relieves considerably the pressure on the bow. Because of the internal force, the wing part of the parasailor² acts as lateral support and stabilizes the sides.
Rolling, yawing, pitching and broaching have been the main risks in sailing under spinnaker. Heavy seas and squally winds can result in even an experienced crew losing the spinnaker or, in the worst case, the whole rigging. The Parasailor uses intelligent, patented technology to shift the sail’s centre of pressure, which reduces this problem considerably. The valve function of the opening in the parasailor² dampens gusts as surplus air can quickly escape but at the same time it creates buoyancy. |

| Cruising Spinnakers are designed asymmetrical in shape and size to be easily flown off the bow of any boat and forgiving to trim so you can set it and cleat it off. |

ASYMMETRIC SPINNAKER
This very modern sail is the best solution for those who want to enjoy open navigation modes without the difficulties of a classic spinnaker.
The DL SAILS ASYMMETRIC SPINNAKER has been designed so as not to need a spinnaker boom. Its navigation angle covers all angles between 60o and 180o. It comes in its own special bag. " |
|
| The ISTEC succeeded it perfectly an alternative to the Parasailor to place exactly between this and the usual spinnakers. Already a simple "single Skin Wing" reduces the unpleasant characteristics of conventional spinnakers and gennakers substantially. |

Hood Sails have been winning regattas and races, including the Americas Cup, since 1952. Today Hood's highly experienced sail-designers, aided by the very latest software, will work with you to build fast sails.
Hood specialise in designing and building racing sails for club racing, classic yachts, short-handed racing (single-handed and double handed) and one-designs that mandate woven sailcloth.
Every sail is individually designed, using the very latest software, taking into account: the exact specification of your rig; how and where you sail; the abilities of your helmsmen and crew; and your budget. Hood Sail Consultants are then available to sail with you to help set-up your sails in order for them to deliver their maximum potential. We then keep you sail design on our database so that, when the time comes for a replacement, we can build either: a perfect replica or, if you require changes, we can fine tune the design to your exact requirements. |

FX Custom Cruising and Racing Spinnakers deliver superior performance with asymmetric and tri-radial designs to cover a wide wind range. Designed by a sailmaker with more than 30 years experience, FX Spinnakers are built using Challenge .75- or 1.5-ounce Nylon, with lightweight, non-porous AirX as an option.

Bill's Asymmetrical Cruising Spinnaker
The innovative Asymmetrical Cruising Spinnaker adds more performance to your cruising inventory than any other sail. Bill molds the spinnaker in three dimensions on the computer based on his America's Cup design development experience. His highly efficient cruising design, slightly smaller than the racing sail, has a tri-radial panel layout with radial reinforcements for strength, durability and low weight. Our easy-to-use spinnaker is versatile, helping to keep your engine off in calm weather.
Your confidence in using it in heavier weather will increase as you learn that its deep entry decreases your boat's oscillations and it performs efficiently from a beam reach to a broad run. Raising and lowering the Asymmetrical Spinnaker can be handled easily by one person with our snuffer-a full-length sleeve that contains the sail while it's hoisted and doused. We encourage customers to have fun in selecting the colors and patterns for their asymmetrical spinnakers. |

Bill's Spider Spinnakers
Bill employs the most sophisticated computer-molded spinnaker design system in the industry, allowing each panel to be shaped separately. These molded panels fit together without distorting the lightweight spinnaker fabric. The result is the most efficient sail for maximum offwind speed. Breakthrough shapes are engineered for performance spinnakers in any size range, from runners for the Grand Prix Maxi circuit to world champion all-purpose J 24 spinnakers. |
|
| The asymmetrical spis are used in race on boats having a very good capacity of acceleration which justifies the increase in roads of these spis which sail between 100 and 150° of the real wind. One finds these spis on the 747, Melges 24, J80 and minis 650 and other fast boats. Just like the symmetrical spis, these spis must also be drawn according to the use and of the characteristics of the boats for which they are intended. |
|
Tri cut radial designed with 4 zones of orientation. The 2 central intermediate zones, allow a reorientation of the right of the wire of roving in the principal direction of the efforts. That results in a great stability of form.
This cut, general-purpose of 90° with 160° of apparent wind thanks to the possible adjustment by the tack, is appropriate for the boats of more than 45 '. She is proposed in option with a decreasing grammage for a profit of weight and a greater versatility. |
|
This radial tri cut, with 3 zones of orientation starting from empointures, ensures a very great resistance to the deformation and a good stability.
This cut, general-purpose of 90° with 160° of apparent wind thanks to the possible adjustment by the tack, is appropriate for the boats of less than 45 '.

| In cruising the spinnaker is without question the sail which gives the most pleasure. By its beauty initially and its effectiveness then which makes it possible the boat to reach averages raised by small time in the greatest comfort of navigation, whereas others sail with the engine. |
|
This spi is ideal for a use in intensive regatta because very general-purpose.
The orientation of the widths confers a great stability and a minimum of deformation to him, as well as a use of roving in its most resistant part.
This cut is proposed with a decreasing grammage in option for a profit of weight and a greater versatility. Cut SCZ3A is adapted to the boats of less than 45 '. |
|
Cut reference for the spis light, médiums or heavy allowing the best distribution of the efforts empointures thanks to its 3 radial zones.
Less sophisticated than cut SC, this spi is appropriate perfectly for a mixed program: 80% cruising and 20% regattas.

| The spi is an air sail, behavior only by 3 points, it flies! This particular characteristic makes of it a mysterious sail, delicate conceive, difficult to analyze and on which one will find according to their origins of the forms which could be very different. On the spis Racing DELTA, our research relates to the maximum of projected surface, synonymous with performance to the back wind, and on a great stability facilitating the access to the best adjustment. |
