Hi all I am just about to replace the standing rigging on my Cav36 in preperation for the RNI next year. I'm keen to upgrade to hamma strand wire but have heard it suffers from fatigue a lot quicker than conventional s/s wire. Has anyone had any issues with this??

Cheers

Hamma Strand is just a brand name of Dyform wire.

Just like Rod rigging you do hear from time to time people making statements like this, that the conventional 1x19 wire lasts longer.

 

If you size it correctly the 1x19 ss wire will have to be a lot bigger in diameter to be as strong as Dyform so in an arse about face way the wire could last longer, but it is much more windage and is heavier.

 

In order Rod is the best, Dyform next, wire a very distant third .

While we have you here Tim, what about rope? How far is that from being mainstream? I know the racers like the weight and windage thing, but as a cruiser I'd love to be able to store a coil of spectra that I could make into a stay simply by splicing the ends.

On the wide stay base of a multi there are plenty of products that already fit that bill Dave, but not yet on a Cav 36'.

 

PBO is a great option to save weight, as well the Carbon Rod rigging is becoming very mainstream, although is still expensive.

 

The very construction (braiding) that allows the quick splice you are after is what gives initial stretch and creep to the likes of Dynex 75, and while a couple of mm of stretch is ok on a multi ,you won't get away with that on the Standing Rigging of e.g. a Cav 36.

 

But it can be used on Runners, Checks etc

Hamma Strand is just a brand name of Dyform wire.

And Dyform is also just another brand name of a compacted wire ;)

 

I have a dude who wants to fibre rigging onto my boat. He swears it'll be the bees knees but I'm very much in the 2 minds place. Mind you he is very clued up and it is the real McCoy rather than the dyneema most here use...... Ahhggg tempted but if it's a cock up???????

 

I wonder if wants to play with a Cav instead?? Feel like being a Guinea pig?
