Står i begrepp att beställa ett nytt storsegel och har inte bestämt vilken duk det skall sys i.
Är det någon som har erfarenheter från X-tech Alumashield (Dimension Polyant), dvs sk \"cruising-kevlar\". Genua 1:an som följde med båten är i \"ren\" kevlar och den är efter 6 år ganska sliten (sprickor i väven på utsatta ställen).
X-tech Alumashield - erfarenheter efterfrågas
7-9 år...
Segelmakaren säger att laminatseglets livslängd är 7-9 år.
Motsvarande siffra för ett dacronsegel sägs vara 8-10 år.
Skillnaden är väl att laminatseglet håller formen hela livslängden medan dacronseglet töjer sig gradvis under hela livslängden.

Ett ärligt svar från en segelmakare om olika material: (norpat från http://www.sailinganarchy.com/ som är en utmärkt sida med kul forum)

Q: If I'm willing to increase my budget for a new genoa, are there any fabric or construction choices that will significantly increase the shape-lifespan of the sail for club and medium distance racing?
Would building the sail out of either Cuben Fiber or Radial Hydranet deliver a sail that could hold an effective club race sail shape for over eight years?
Assume a 40 foot masthead keelboat, roller furled, with the priorities of:shape, life span of that shape, and the sail in use for about 400 hours per year.
A: Increasing your budget isn’t going help; I don’t know of any fabric that will really hold its shape for 8 years as a racing sail. In all honesty a good Dacron cross cut sail will probably be the closest you get.
Cuben fiber is definitely out, as is any other laminated racing type fabric. None of them are going to last 8 years, let alone last 8 years with good shape for 3200 hours of sailing; and keeping any of them on a furling system will only make the longevity worse. The radial hydra-net will probably last that long, but it certainly won’t have the same shape it had for the first few years, and it is really too heavy for a racing genoa on a 40 foot boat. The lightest Hydra-Net 343 Radial cloth weighs 8 oz. The cruising laminates are similar; they will probably last that long but they won’t hold a racing shape that long and they are all very heavy for this size boat.
The closest thing that will hold a competitive racing shape is the Challenge PinStripe Aramid. It is a radial Dacron with Aramid fibers woven in. I have seen sails that have been very competitive after 5 or 6 years of sailing but that is certainly pushing the limit.
Racing laminates with mylar on both sides are good for 2 to 4 seasons depending on how critical you are about shape, and will probably physically wear out in that amount of time. Laminates with a taffeta on one side will hold their racing shape about the same but will get another year or two of use before they physically wear out.
Hydra-nets and Cruising Laminates are very heavy for a 40 foot boat genoa and may last 8 to 10 years depending on use but their racing shape holding won’t be as good as a laminate racing fabric.
PinStripe aramids will last 5 to 6 years and their racing shape will generally last 1 to 2 seasons more than a similar laminated fabric. They are generally a little heavier than the good racing laminates.
Dacron will last 10 to 20 years depending on use. It will never hold its shape quite as well as a racing fabric, but it also won’t change as much over time.
