Regarding the use of 7 mm Titan, here is a clarification from Scott at Bluewater Ropes. See below: Scott Newell wrote:From: “Scott Newell” To: Subject: RE: [from Canyons Group] Re: GEAR: Bluewater Canyon Pro rope specs Date: Tue, 10 Sep 2002 11:33:00 -0400
Again I apologize for the website not being updated in a timely manner. Re: 7mm TitanThis is a braid on braid that we do not recommend for canyons. It is an older design with a different sheath construction that will not work as well as the canyon and Canyon Pro constructions. Re: Abrasion quote is for cycles to total failure. The description in the catalog reflects this as it refers to the Spectra core fibers versus other fibers. The Canyon and Canyon Pro do have specially designed sheaths to provide better abrasion and performance characteristics in the sheath. Canyon and Canyon Pro both have a braided sheath over a stranded core which is safer than a braid on braid.

I emailed Bluewater asking about the Canyon Pro rope because it wasn’t on their web page either. Apparently they will be updating their web site to include the Canyon Pro web site some time soon. I imagine it is the same deal with the catalog.

> I emailed Bluewater asking for the specs for the Canyon Pro rope. Here is an excerpt from the email I got back:===8mm diameter5000 lbf tensile100% Spectra core100% Poyester sheathWeight per 200 ft.= 5.75 lbsThe Spectra core does not absorb water so the rope will remain light. This rope buoyancy is neutral. The sheath comprises 57% by weight and 56% by total yarn denier. Retail price is expensive @ $1.09/ft. due to the Spectra core.=====
I downloaded Blue Water catalog (from website), but there’s no Canyon Pro rope … Is it out of production?
I found “Titan 7mm” instead, very very interesting … Titan is made of Spectra and nylon, and here’s what they say about: ************************* Tensile Strength: 26 kN (5750 lbf) Weight per Meter: 36 g UIAA Certified (test G-1) (does someone know what is this test? any URL about it?) It does not lose significant strength with repetitive flexing like other lower cost “high performance” fibers. Spectra offers a huge increase in abrasion resistance over the core material used in similar cords **************************
I feel attracted by its low weight, the strength (IMHO much more than we need, don’t forget we rappel on double ropes) and the declared “huge increase in abrasion resistance” which IMHO is a main feature of good canyon ropes. I don’t understand how core can increase abration resistance (a work usually made by sheath) however.
“Titan” might be better then “Canyon Pro” … lighter and stronger!
Now the question is: how can a canyoneer from Italy buy Titan (or Canyon Pro)? In Europe are sold european ropes … If you know an online store selling Blue Water Titan or Canyon ropes please tell me.
