question Mainsail traveller for Mark V (Superfil dans)
Posted: 11:09:28 am on 7/13/2012 Modified: Never

I'm currently looking to improve my mainsail traveller. I have looked to install an Harken windward sytem (midrange boat size) but I'm not sure that will fit the scape allowed for the track and the car.  So if anyone have any suggestion, it will be greatly appreciated.

Thanks a lot.

Definitely windwards sheeting is the way to go. Still Knot Working and Distant Thunder both have them.  I am hoping to finally install one on my boat next week.  It is very important to note that the Harken windward sheeting cars available now are the CB (captive bearing) type.  These will not fit on the old tracks.  Additionally, the new tracks designed for the CB cars have a different hole spacing 4" to 100mm.  Options are either to find a windward sheeting retrofit for your existing traveller (Steve Reid managed to get one).  Or you need to 'Special' order the RETRO track with the CB groove and 4" hole spacing - 4-6wks delivery.  Enjoy!

Are is the size of the windward system are you planning to use?  As per spec of Harken, the small boat size is very close to the load charge it can handle base on the mainsail size of the mark V.

Please let me know what you will use, and I would appreciate if you can provide me pictures of your installion.

Thanks for your answer.

Sorry it took a while to get back to you but it isn't a 'quick' project.  

Small boat car is right but with the 'Hi-Load' optional Torlon bearings.  As I mentioned before, unless you can procure a retrofit to your old traveller car you will be buying the new "CB" cars with Captive Bearings.  This is great because you don't need that little blue piece of plastic but what it does mean is you have to replace the track.  The CB cars have a stainless bearing retainer that requires a new CB-type track.  Additionally, as mentioned before Harken has shifted from their original hole spacing of 4" centres to 100mm.  mkVs were installed with the 4" centres so unless you want to fill and then drill new holes (might not be a bad idea) you need to order the RETRO track with a slight premium and a huge delivery time.  Removing the original track requires you to pull all those round 1" diameter plugs down and also pull the electrical panel for the centre 3 screws.  After its removed trim the new track to fit the existing.  I had found that the outer screwholes weren't drilled.  The ends will have to be drilled and taped for the end cap (Hi-Load Red Ones).  Installing the track is nothing fantastically complex but very fiddly.  The 10-32 nuts and washers are hard to replace by sticking your finger up the 1" hole in the liner.  As I installed the track I was caulking the bottom of the track around the screws with 5200.  The residual guck on my fingers ended up helping hold the nuts and washer on my finger as the screw engaged the first threads.

Once the track is on you simply slip that expensive little car onto the track, rig the control lines as per the diagram and you're set.  I did find that the traveller control lines were too short compared to my previous setup which I thought was 3:1.

Not sure if I've missed anything, hope this helps.

There is another solution to the hole spacing issue. Harken makes a slotted traveller track, it uses sliding nuts that allow you to fit any hole spacing. Check out the Harken catalogue pages 98 P/N 2721 or pg. 104 P/N 27HB.
