like i said its not the actual fibres but the glues used to hold it all together in laminated form.
the glues just haven't got anywhere near being useful for anything more than short term racetrack orientated solutions.
in testing and i was on steve's boat at the end of last year testing a new glue compound and it was clear after 4 days that the problem wasn't the material it was the glue.
the material thats used is fine - the weave on its own is fine but for it to work
as intended it has to be laid up in laminated form. the reason why most of us race
track boys n girls are not choosing it for kites is cos of the amount of abuse that a kite gets - it's far far bigger than a number 1 headsail and takes far more punishment than a mainsail
but under testing conditions there were problems with the glue becoming "unstuck".
Cuben Fibre was designed to be an ultra lightweight sail capable of going long distances over short periods of time. remember this nearly every VOR boat swaps a full suit of sails out at every stopover -- so that sail might only have covered a few hundred miles but it gets swapped out cos its tukd -- add into the mix that a VOR project
will be running a budjet of many millions of pounds which means that they can afford it - us guys on the other hand have a budget
of maybe £6k per year for sails -- so for that means i can have headsails and i get a mainsail
every 18months or so.
CF is the next generation PBO and that didnt catch on cos of similar issues - the glue used in the PBO sails reacted with the UV and caused it to fail a lot quicker -- the glue used in cuben fibre sail production is a different mix to the stuff used in PBO but its still unstable -- until someone gets a mix thats stable and can be used time and again like they do with carbon and kevlar then its pretty much upto the Sheiks to make it happen.
in cruising terms of kites stick to what everyone has been using for years and works and costs a lot less
if like me you're looking at over 100sqm for a kite then stay away from laminates for a few more years until you see the IRC racetrack boys n girls using them --- the IRC guys are your average club sailors with extremely limited budgets and might only buy headsails and mainsails and like me they'll get kites and other sails repaired
