[Public-List] Nylon vs. Dacron rope?

[George Dinwiddie]

David,

You're probably right that the one with a shackle is a spinnaker pole 
lift, in which case it would be dacron. The others might be spinnaker 
sheets, which would also be dacron.

The principle reason for choosing between dacron and nylon is the 
stretch characteristics. If you need a piece of nylon for it's stretch, 
you could try stretching it and see how stretchy it is. Old nylon might 
not be as stretchy as you like. Conversely, old dacron might stretch 
more than you like for non-stretch applications.
