Hi all,

is there any rational reason, why a main sheet should contain dyneema?. On large boats with winches I understand it, but on a beach cat... Diameter would be around 8mm or more and you will not pull with more than 50kg on it, which is 1/30 of the breaking load of a simple polyester 8m sheet. Stretch would be about 8%*1/30 = nothing, you will sail it anyway from the hand and not cleated... So why dyneema <img src="http://www.catsailor.com/forums/images/graemlins/confused.gif" alt="" />
I use simple plain 8m polyester, it doesn't kink, holds in the cleat and on the ratchet, but it doesn't look Gucci.

What about the spi sheet? Here I looked around for the lightest stuff for 8mm diameter and not water absorbing. I found 8mm life line (the yellow - red stuff), easy to splice, light and with 0.70€/m also cheap.

Is there any other property of dyneema (other than strngth and low stretch)?

Cheers,

Klaus
