[Public-List] Mooring Pendants Double braided or 3ply?

[Gordon Laco]

As usual - I am pleased to offer my opinions...

Three strand rope is certainly stretchier than double braid.  Along with the
whatever stretch inherent in the material the rope is made of, three strand
has more 'mechanical elongation' due to the rope unwinding a little when it
is under load.  

R&W Rope in New Bedford makes mooring pendants to order www.rwrope.com
(I'm not involved in that so I don't think George will mind me adding them
to the list of people who supply pendants.)

Generally speaking, double braid has slightly higher strength ratings for a
given diameter than three strand and is considered more abrasion resistant.

I always used three strand simply because I liked the way it looks better
and also because I think it is more fun to splice.

A funny thing is that in Europe, people commonly use UV stabilized
Polypropylene (NOT the yellow stuff available here) - it has very little
inherent stretch - and we are raised here to despise that material
(admittedly in the un-UV stabilized form)

My two cents worth...
