Re[2]: [at-l] tevak weirdness

[tmcginnis@ucclan.state.in.us (Thomas McGinnis)]

     In doing research for lightweight backpacks, I found the most 
     knowledgeable current users of arimid (kevlar) based and Spectra based 
     products were sailmakers. I know you all want to know this, but arimid 
     fibers have lower UV resistance when compared to Spectra, while 
     Spectra has an alarmingly low melting point (around 250 degreesF?). 
     Arimid also has less stretch than Spectra, while Spectra has the 
     advantage with regard to strength. What this means is that your Wild 
     Things ("Technora"/arimid/nylon) pack will be slightly heavier, will 
     weaken in the sun, but won't stretch as much or melt as fast as your 
     Kelty White Cloud. Again, I know you all wanted to know this. But 
     neither of them will absorb much in the way of water...which is good 
     for Spectra especially, since it won't hold dye or urethane or 
     nuttin'!

 "gear heads" have them. the terminology is strikingly familair to this trail 
 related stuff. they used other terms too that seemed to soudn like some off 
 shoot of this list.  but they slipped my mind now.   just an interesting tid 
 bit i saw..  weird stuff isay weird sutff. i wonder why a sail has to be 
 ultralight?  hmmm any sailors/hikers on this list? >>
on a sailboat you carry several different sails, and they can weigh a 
bunch...the higher a boat sits in the water, the faster it can go.  I dont 
think they are so much concerned about the weight of the sail in the air as 
they are with the ten or so below deck.
