![]() The tack line is 3 to 1 at the furler and leads to a winch, so serious luff tension. After the experience with the first code zero I made sure that the new one had an anti torsion rope and furler. Not as good as a genoa but it does not carry a punitive penalty. A small, flat, light wind code zero designed to be a windward sail, I can carry it at 25 -30 apparent with a true wind angle of 55 -60. The second is from a local sail maker, Kevin Farrar. Al spinnaker asimétrico lo llamamos también spinnaker multiuso o MPS o. Por ejemplo, chute, blister, splister y gennaker. Su evolución, en combinación con sus diversas formas, ha hecho que reciba diferentes nombres. This sail now has a anti-torsion luff rope and furler and gets a lot more use. GENNAKERS / MPS / BLISTER (ASIMÉTRICO) Hace unos 20 años varios fabricantes de velas diseñaron el spinnaker asimétrico. At 7 knots true I am getting overpowered and need to bear off a little. With it I can sail to 30 apparent with a true wind angle of 65 -70, so not a windward sail. The first is from North when I built the boat in 2000. Both have a low stretch luff rope that minimizes luff sag. If you want a windward component I am skeptical that a cableless code zero will be able develop enough luff tension to go to windward at all. An adjustable tack is recommended to get the most out of the sail: well eased for downwind and tightened up for. ![]() I carry an asymmetrical spinnaker on my cat which draws well running deep angles and up to a little higher than 90 degrees apparent. If so the cableless sail will probably work. A well designed asymmetrical can be a very versatile sail. A screecher and a code zero are the same thing. Gennaker is just a general term for a potential downwind sail, a cross between a Genoa and an asymmetrical spinnaker. The term gennaker can cover a code zero, screecher, or reaching spinnaker. It sounds like you normally use symmetric spinnakers and want a code zero to fill in as a reaching sail. Code zero is another name for a gennaker. A Code Zero Laminate will provide both lightweight performance in light air, and durability while crossing the pacific for an offshore catamaran cruiser with a displacement of 15,000 KG.I think that you really need to define what it is you want the sail to do. Finally, laminates are very performance orientated, with low stretch and very consistent sail shape there’s also so much armamid in the Code-Zero laminate cloths that it’ll push your boat over before causing damage to the cloth, making it great for offshore sailing. Heavier woven cloths, such as a 4oz Dacron, will provide durability and if you’re leaving the sail up for weeks at a time, Spinnaker Nylon is very lightweight 1.5 – 2oz, and will allow you to sail in very light winds. As a baseline, Precision Sail’s code zeros are designed with a zipper luff to allow a torsion line to be added/removed for storage and cleaning. It’s important to know if you are going to need a sail that is more durable, lighter weight, or more performance driven – each of which has advantages and disadvantages. It's important to understand when (and how) to use each sail. ![]() But you can't just raise any sail and go for it. Want to go downwind fast Use a spinnaker. As Code-Zeros are run at varying degrees and can function at a reach it is easy for sailors to push the limits of the intended speeds and angles causing damage to the sail. Most sailors use additional sails for different conditions: the spinnaker (a common downwind sail), gennaker, code zero (for upwind use), and stormsail. Code Zeros can be made out of either Spinnaker Nylon, a lightweight Dacron, or a Code Zero lightweight laminate (such as Contender ZL series). ![]()
