gennaker/code 0 furler

[marcot]

I'm about to buy a Facnor Fx 4500 furling drum to be used with my gennaker.

I do not have the antitwist cable and I wonder if the gennaker will furl properly.
I like to share experience.

I have a Bartels furler on a gennaker. The sail doesn't have a torque rope in the luff, the furler works well and the single line doesn't slip. However, it can be difficult to furl the leach of the sail if you try and furl it in anything above a light breeze, the leach doesn't furl and tends to form a "bag". it takes the power out of the sail and allows it to be recovered, but its not neat.

I've also used a furler on a high aspect ratio No3 genoa (which had a Kevlar torque rope in the luff) and had the same problem, it wouldn't furl completely and I finished up with a flogging leach from about half way up the sail.

I hope this helps.

I have the a Facnor FX 2500 with the AFX kit.
The Facnor solution for furling a gennaker consists of a top and bottom swivel and a anti twist rope connected to a central furling line, that is what I have (the AFX kit).

If you have a deep gennaker like have I think furling w/o the anti twist rope is hard.

You can either go for the Facnor way
or
You can adapt the FX to do top down furling as the competitors do (in that case you will only need the bottom swivel and the rope).
I have been planning to test the top down conversion on mine - but have not done so yet as the central rope is fine

in this picture you can see the anti twist rope and the furler

Here is a picture of my Code0 on the same furler, this sail has a anti twist rope sewn into the luff

Both these sails are easy to furl.

knuterikt,

Thanks very much for the pictures, I hadn't seen the idea of a torque rope to the head of the sail before. The picture are great and set me on an internet search. I found some Youtube video of the system working and looks just what I need.

I'll look at my Bartels system this weekend and see how it can be adapted from a bottom-up furler to a top down furler.

Any advice on what type of rope to use as a torque rope?

Good you could use my pictures - a little bit large but.

The one used on my gennaker came with the kit from Facnor - have been using it for 5 years now.

The one used on the Code 0 was put there by the sailmaker.

I would think that a good (real) sailmaker and a good rigger would stock this kind of ropes now, as they are being used a lot these days.

My rigger http://southerncross.no/en/ switched to Marlow ropes last year and it sounds like he have found the "anti twist" rope from Marlow to work OK, I guess that he is using this http://www.marlowropes.com/leisure-marine-products-1/cruising-racing/prodrive.html

I have anti twist rope on the luff of my code 0, works very well, can furl it in 10 knots apparent.
Harken single line furling kit.

Having found above researching further after visiting LBS and speaking to a few people I wondered if the Bartel version is better than say Selden or Karver versions? One sailmaker seemed to recommend Bartel but others have suggested Karver so now confused. They seem to be in the same price range? But are there other options I should look at? I current have the sail with Snuffer so should I just follow advice of sailmakers as to make or are there ones to avoid at all costs?
