      Abbreviated rules   07/28/2017

      Underdawg did an excellent job of explaining the rules.  Here's the simplified version: Don't insinuate Pedo.  Warning and or timeout for a first offense.  PermaFlick for any subsequent offenses Don't out members.  See above for penalties.  Caveat:  if you have ever used your own real name or personal information here on the forums since, like, ever - it doesn't count and you are fair game. If you see spam posts, report it to the mods.  We do not hang out in every thread 24/7 If you see any of the above, report it to the mods by hitting the Report button in the offending post.   We do not take action for foul language, off-subject content, or abusive behavior unless it escalates to persistent stalking.  There may be times that we might warn someone or flick someone for something particularly egregious.  There is no standard, we will know it when we see it.  If you continually report things that do not fall into rules #1 or 2 above, you may very well get a timeout yourself for annoying the Mods with repeated whining.  Use your best judgement. Warnings, timeouts, suspensions and flicks are arbitrary and capricious.  Deal with it.  Welcome to anarchy.   If you are a newbie, there are unwritten rules to adhere to.  They will be explained to you soon enough.

Adjustable Genoa Blocks

Recommended Posts

Why? No, seriously because the application, your goal in having adjustable cars, will make a difference in the answer to your question.

I'm considering adding adjustable genoa blocks to my Hanse 370. Any experience? Worth the $500 investment? Garhauer vs Harken?

 

If you need to make adjustments under load your best solution is to do it with a ball bearing car and a 4:1 tackle. Harken is a very good option and will be reasonably priced. Any system that slides over a T-Track or a simple slide type of car will creat a lot of friction to move under load.

 

What system do you have now? this is important because most , if not all, traveler systems are incompatible with each other; so let's see what is there first and try to find a solution using the same track.

In this article I describe the way we make our adjustment for sailing off the wind. We use a jib sheet twing rather than moving the car. It is easier to do. If you are moving the car because you are partially furling a jib, then the adjustable car, Garhauer makes a nice ball bearing one for not much money, would be better. http://L-36.com/twing.php

 

I sailed on AC-76 last weekend. They are using a jib that is really too small for the way the boat was set up as they are taking tourists out for a ride and not defending the America's Cup. They used a jibsheet twing to make the final adjustment. It was a very big strong ring for a very large sail. The TP-52's rely on jib sheet twings for the jib lead. The jib track and car feed the control line to the twing ring. The sheet does not go through the car, just the twing ring. It is really something you should consider as an alternative to a movable car.

@Allen - Those are called "In Fuckers". Been around a long time...

 

@Silver - Go with adjustable jib car tracks. Harken is good. Worth the investment IMHO

Hi Silversailor,

 

We just did the same upgrades to a couple of similar boats of your boat (Dufour 38 and Grand Solei 42). Definitely HARKEN for a low friction system. It is worth the money as it will allow you to depower when the breeze comes up or to move the lead all the way forward for close reaching. The following are the parts you may need for a 3:1 system (we are assuming that you don't have a ball bearing track) - let us know if you will prefer a 4:1 system as some of the part numbers will change:
HARG273B_T.jpg

Code: HARG273B
Price: $297.84
HARE2750_T.jpg

Code: HARE2750
Price: $200.82

HARR2712M_T.jpg

Code: HARR272M
Price: $122.23
HAR1523_T.jpg

Code: HAR1523
Price: $41.76

Note: You may need to add a Harken 150 camcleat per side (with fairlead) and footblock if you need to divert the genoa lead line.

Note about pricing: Call us for a friend of Sailing Anarchy deal (not sure how we can make it work with $500 but will do our best).


Do not hesitate to give us a call to go over it or let us know if we can provide you with any additional technical information.

Best regards,
Juan Mauri

It takes careful design and thought. The twing setup is simple, but you need two winches and normally the secondary which will take the twing is further aft.

 

New cars is just the start since you need some leads to get the control lines to the right place.

 

What problem are you solving? Around the buoys or long distance? Moving the lead for 30 minutes 30 hours?

Harken is the go to solution.

 

If you can handle a bit more friction and probably the ability to adjust the car forward when close hauled in a breeze, Garhauer is an affordable option that runs on existing T track.

 

As asked earlier, what are your objectives?

Simple CHEAP way for occasional adjustment is a relieving line. Can be just an old spare hunk of line with an eye hook (cunningham hook works well) tied to the end. Put the hook in the clew cringle, tighten to take the load of the genny sheet, adjust the car, release the relieving line and adjust the genny sheet.

To answer some of your questions: we do JAM club races and distance races (just completed the Milwaukee, WI to Ludington, MI across Lake Michigan Queens Cup 81.1nm) as well as lots of cruising. My existing track is only about .75" wide with a Harken car. Would need to upgrade track as well as adjustable cars. You have offerred lots of good suggestions. The ring on the twing line seems like a low cost alternative that can accomplish everything that a movable genoa block system can do. It's easily installed before races and can utilize my secondary winches. Allen, can I get you to make some of those soft shackles for me?

 

Thanks all.

Sorry to take so long to reply. Somehow everything is going to the spam folder. The soft shackles are pretty easy to make. Here is a link to the best kind http://l-36.com/soft_shackle_9.php They really are better. Endorsed by Brion Toss and all that. If you have any questions, just let me know.

 

Not sure if this came out but if your need for the twing is occasional and you have lots of room, a locking carabiner works well. Don't even think of using a spring loaded carabiner and use one with a completely round cross section (lower friction). The spring ones will lock themselves to your lifeline and get stuck forever in your jib car. Don't ask how I know. I use round rings on my jib in a permanent setup where a single ring serves both the twing and inhauler. For the big jibs, we use the locking carabiners. Just hook them up when and if needed. They go to the secondary winches.

 

One thing that was not mentioned about the adjustable jib cars is that there is a lot of line associated with the control line. It can be a pain. The twing may need a winch but the line is 1:1 and isn't getting in the way all the time.

I've had 4 different boats, all with Harken adjustable genoa cars. I adjusted the leads frequently, and the system is easy and glides under load. That's my total input.

I have had harken and garhauer both. Harken is the best, but Garhauer is a close second, especially when you consider you get to use your existing track. Customer service is superb from both. Go to one or the other, you will love them!
