Does anyone understand how this works? Assuming (big if) the towable car fits on my existing track, it has, or can be specified with a turning block so that a 2:1 purchase can be achieved with another block on the end fitting. However the Barton end block doesn't have a becket so I really don't see how you can make this work?
 
You would start with the control line permanently made fast to the forward mounted end stop, feed it back through and around the sheave in the car, forwards and around the sheave on the forward end stop, then lead it back to a cam cleat or clutch at the cockpit combing.

The car only needs to be held back. As soon as the control line is freed, the car will generally move itself forward. [Edit... I have corrected this direction info in post #7. Totally back to front and I'm blaming it on Long Covid brain fog..I'd also add now that it's easier adjusting the windward side car forward before a tack then making whatever adjustment aft after the tack by just slackening the control line. The car must therefore move back by itself!!! End edit]

(Sorry if this is granny sucking eggs category but I didn't know if your question was about barton parts availability or about how the system would actually work).

I don't know why the Barton photos show the loose end of the control line just disappearing when it would usually be taken aft to where the crew might be able to reach it.

What you say is exactly what I imagined but the only Barton end stop I could find wouldn’t allow that - I haven’t seen the end stops in post above available anywhere

Would the car not move aft if the control line is released? The tension on the genoa sheet would cause the aft direction. The control line is for restraining aft movement and hauling forward the car.

Or have I misunderstood?
 
Darn... I know this long covid has reduced my concentration... I really can't think about two things at once.. work and genoa car mechanics just don't combine well.

I think everything else i wrote was fine but I just haven't got the concentration span for long enough to re-read...

Let go on the genoa car control line and of course the car will shoot to the back of the track...

Commiserations - I've just finished my first year as a Long Hauler. It's the worst club in the world! I only knew the car went backwards as, through sheer coincidence I'm buying some second-hand kit and had worked it out in advance.
 
OK I think what Barton shows on their website is the current system and what some resellers like Jimmy Green are showing is an older system. It all depends on whether they fit my existing (IYE?) track

Thanks... I took the boat out once last year... I hate to admit it but couldn't cope with chatting to crew and motoring back into the marina at the same time.. Shook me up... I think giving replies here without having the concentration span to proof read my reply is also bad on my part..
Grrrr...

I might stick to just thinking about things until my concentration and energy is back to normal.
 
We’ve got the Fredrikson equivalent. The car does go backwards, the tow line pulls it forward. Ours is only 1:1, we put a stopper on the jib sheet and use the jib winch to pull it forwards. So just a turning block on the front end of the track. Itks actually easy to do like that, and as you need to winch them anyway unless theres no wind, why bother with 2:1?

Same with our Lewmar NTR system. The upward pull on the sheet causes the car to move back. The control line pulls it forward.
