Where to buy spectra??

[Guest]

So where do you all get yours from, any difference in brands (Nautilus, Donaghys, Fine Line etc). Are some places cheaper than others?? Have to replace all the halyards on a Y88. Cheers, Dan

Chains ropes and Anchors. Someone wil correct me I am sure, but I think it is found on "The North Shore". Over that way anyway. You will get the best advise and help of anywhere.

If the tightarsed prick were to pay for an ad on Crew.org.nz there would be a link

[Mothership 6]

Pay for an ad? He should be paying rent the amount of time he spends here

[wheels 543]

Hmmm, maybe I should get a back hander out of him for that too huh

Actually, is there anyone advertising here that handles rope etc at all?? I couldn't see any add leaping out before I posted about CRA

[Guest]

Spectra is only available from Donaghys in the form of their 'Spectraspeed'. Everyone else, inc Donaghys 'Superbraid', uses Dyneema these days. All but one in the Sth Island uses SK75, the one down south uses SK62. 75 is far better than 62 and the spectra. The Spectraspeed should be a bit cheaper than the SK75. Vectran is also a highly viable halyard option and should be pretty much the same as a good SK75 price.

 

Basically Donaghys and Fineline are very good manufacturers and their products are very comparable in performance even if some numbers would suggest otherwise, that's just a 'how they report it' thing. At the end of the day most manufacturers use the same raw product from the same supplies (there is some raw yarn monopoly action in the world) and the same machines to make it. The differences are often no where near as wildly different as the respective marketing Depts would like you to believe.

 

There are some imported versions as well but they are no better and cost more. The NZ made is just good as everyone elses, in fact Fineline and Donaghys export a surprisingly large amount to the world, container loads, and doing that against some very big well financed big brand name competition. Some current TP52's, just as one example, have all NZ made ropes aboard so there is a good example of the quality and performance level of the local stuff.

 

See the team at Sailutions (link above top right) is one option. They know their game well and have good shite.

 

 

I'm told that that the CRA outfit is working on a plan. Just has to be a tad careful due to their position in the market supply chain*. They have been repositioning themselves to beable to present a more public face without pissing off too many. The market is changing quite fast, sadly many in it can't come to grips with reality. There is also a potentially huge OSH issue which prevents too much of a public face at the moment.

 

* to be honest I don't actually quite now what that means but it sounds quite cool and has the word chain in it

Don't the guys at Sailutions sell the Nautilus braid, the SK62 stuff??

They have seen the light and swapping to Fineline as I understand it. Ask, they are honest enough to tell you

As I understand it, spectra and dyneema are the same thing, different brand names....

 

I have been told by a very reputable sailmaker that it is much better to use Vectran in a halyard than spectra/dyneema. Something to do with less stretch/creep (I forget which).

Of course, we were discussing dinghy's at the time so perhaps the ability to crank the halyard on a winch negates any disadvantage of spectra?

 

There are lots of places that sell the stuff. Fosters in town have been very good to me in the past, otherwise Burnsco, Sailors Corner, Boatbits in Takapuna... Just about every chandlery I know of stocks Spectra or Dyneema.

If you want Vectran, try Southern Spars and Rigging (who have a small retail shop with rope/blocks etc) or try a rigger. The one at Gulf Harbour Marina is particularly good, but I'm not sure what they stock...

 

Either way, I would speak to a Rigger first as they will be able to advise you on the best rope to use.

 

Edit: Gulf Harbour Rigging is particularly good... They just recently replaced all the rigging on me fathers mast - good job at a good price.

 

In response to Sailutions, I have only been in there once to get grease for the furler, they were VERY good.

Dyneema and Spectra is spun from UHMWPE. In otherwords, a form of Thermoset Polyethylene.

Vectran is spun from a liquid crystal polymer. Chemically it is an aromatic polyester.

[Guest]

Spectra and Dyneema are a little different and made by 2 different outfits. Honeywell make Spectra and DSM make Dyneema, the raw yarn that is, neither make actual finished rope out of it though. In use they can be regarded as pretty much the same thing though, assuming you match the differing and growing number of 'grades' i.e. SK62, SK75, SK90, 900, 1000 and etc. The SK's being Dyneema and the others the Spectra. At the moment most use Dyneema due to, or so I'm told, slightly better numbers for the buck.

 

The raw Spectra and Dyneema yarns are made by only those 2 respectively. There is some knock-offs now starting to come out of the east but they are still getting up to speed (can be read as dodgy in quality) and some of the users have been screwed by DSM and Honeywell due to patent infractions. They can get at the Asian manufacturers but can those outside of that area that use the fibres. Donaghys and Fineline have expressly told us 'we ain't going there' in respect to the knock-off yarn..

 

Yes Vectran is a very good halyard option and what I choose to go with on main and headsail. The main difference between that and dyneema (the same applies to spectra) is that Vectran doesn't 'creep' under big load. Creep means the rope gets slowly longer, bugger all really but it is there. Knot so important on halyards you play with a lot but if you want a fixed set and forget halyard or are planning on having a sail hang off it for a long period, Vectran is probably the better option.

 

Vectran should be available most places also. The Donaghys version is called 'Challenge Braid' and the Fineline is called 'Premier'. Again both are good quality ropes.

I heard of leaky homes but this leaky ropes is something new to me . But hey i live down in the Bay.

Nothing leaks if you don't get rain huh SJB

LCP polymer molecules are stiff, rod-like structures organized in ordered domains in the solid and melt states. These oriented domains lead to anisotropic behaviour in the melt state, thus the term "liquid crystal polymer." Vectran fibre is formed by melt extrusion of the LCP through fine diameter capillaries, during which the molecular domains orient parallel to the fibre axis. The structure's high degree of orientation translates to excellent fibre tensile properties.

 

For the more technically minded.

 

Yes, copy and paste

LCP, so I wonder if you can get it to light up if you apply a voltage to it

[Guest]

Have to be a lot of volts I would think but you an get ropes you stick a battery onto one end and they will light up. One I know of only needs a AA to light up 30 mts odd, very clever stuff.

 

The real question is if you connect a LCP rope to the interweb, can you indeed get porn sites

OK wise guy, how the hell did I do that?

[wheels 543]

It's all in where it gets plugged in AA. No wait, I think that is when you light up.
