John,

I am hoping that you can elaborate on the above. I was talking to a
well-respected Seattle boat designer who suggested that carbon/kevlar
weaves are an excellent material for kayaks from the standpoint of
durability. (Fortunately I haven't yet acted on his advice.) He claimed
that the carbon/kevlar weave avoids the excessive brittleness of carbon
and the excessive flex of kevlar. To back up his claims, he has some
"squares" of various composites (complete with gel coat) which he bangs
on with a hammer to simulate the effects of impacts. (Some of you may
know to whom I am referring.) The carbon/kevlar weave did in fact seem
to tolerate this treatment quite well. 

I had been planning to order another kevlar boat, as I have found my
current kevlar boat to be quite resilient, in spite of rather rough
treatment. (I have gouged out the gel coat where I have had heavy
impacts with barnacle-encrusted reefs, but I have had no gel coat cracks
or any other damage.) However I was told that the carbon/kevlar weave
would be even more durable than kevlar.  

It is difficult to get information on this new material. Any experiences
that you might be willing to share would be most appreciated, as the
stuff ain't cheap.  We certainly don't want any more paddlewisers to
hear the sound of one hull cracking!
