Movable Genoa cars for DS43

[manaia]

Hi all,
I am thinking of making my genoa cars movable.
My DS43 currently has a block at the front of the track and the genoa cars have a hole for a shackle (no ropes or other equipment).

Does the standard setup allow only for this single block, ie. the line runs from the genoa car through the block, back through the leads to the jam cleat (near the primary winch), perhaps I am missing some equipment?
What size line is used (will 8mm or 10mm be required) and is there enough purchase with one block to move the cars ok?
Any suggestions welcome, thanks.

Yes, that was the standard setup on my 43DS - line from a jammer close to the genoa winch running to the front of the genoa traveler through a sheave and then back to the genoa car where it was attached. There is quite a bit of tension on the line if you have the car all the way back and pressure on the genoa and try to winch the traveler forward, but not close to any breaking point on 8 or 10mm line so it is more important that the line be sized to what your stopper/jammer supports.
I've got the 43DS manuals at www.sv-zanshin.com/manuals/jeanneaumanuals.php and the line width there isn't specified but I seem to recall it was the same diameter as the 10mm furling line.

Hi Zanshin,
Thanks for the info, I'll set it up on that basis.
Also the manual is very useful to have in electronic form, so thanks for that too !

No Worries.

I have a 4-1 for my jib carr's, I could not imagine trying to do a larger genoa/jib as you two have with only a 2-1! You should be able to do a double height block setup forward, a single with a becket on the carr itself, this will get you into the 4-1, so makes it easier to pull forward in a bit of a blow per say. BUT, even still, you will probably have to let the jib sheet out some. Then attach a line to the rear of the carr, to pull it back helps some too, if the carr will not go back from line tension to the jib.

MartyB -

You can see it in the picture linked to by the thumbnail below:

Yes, I have been wondering about the number of purchases, but will try it at 2:1 to start with.
I imagine it will be most useful when rolling up the jib and want to move the car forward. when un rolling, it appears that the pressure from the jib sheet will move the car backwards. The biggest advantage is not having to leave the cockpit to make the adjustment !

And backward is easy enough? On my SO35, moving the car back is not an easy task either (forward nearly impossible).

[MartyB]

I'd agree with renegade, granted my carrs are not roller types, I use ALL the 4-1 for pulling te car forward at times, pulling back get interesting, at times we still have to kick it back. I can see the need for a double high forward, single on the car with a becket.

Here is a link to how I concocted my line setup. I can personally see a better way if you will, but I had most of the parts to use pin adjustment, then modified a pin adjustment carr to work with line adjustment.

I do agree, it makes it such generally speaking with my boat, one does not have to go forward to djust, make a couple of tack to adjust the leeward side while it is windward etc.

That's really interesting about the difficulty to move the car backwards. In the past I have always found that the cars will fly back if the pin has not been properly set!
I am going away on the boat this weekend and make the changes. There is a good 20 knots forecast so I will let you know how I get on. Regards.

Manaia, I'm sure the differences are in the boat and hardware. Mine is a 2006 SO35 - mostly Harken outfitted, and I'm reasonably sure the blocks and tracks are Harken as well. Even well lubricated, the blocks don't move smoothly in either direction with any load on at all. Marty - I also usually use a gentle "kick" when moving backward, each resulting in a short movement.

Hi all, after a false start (wrong size shackle) I have fitted the lines to the genoa cars and they work well.
I have found that easing the pressure on the jib sheet allows the car to move backwards, either luffing or easing the sheet seems to do the trick.
The same applies for moving them forward, i dont want to try and use the winch as the lead doesnt seem fair.
A big improvement for us !
