new pin holes in jib tracks

Our Niagara had holes 4 inches apart and I drilled new holes half way between the existing ones on the track. The holes only have to go as deep as the stopper pin and using a cordless drill it was very easy to do this without going too far. I did not use a stopper.

Our current boat has an adjustable car system with lines, etc.. .and is certainly a much nicer system - especially the leverage to move the cars forward under load. However it would indeed be expensive to convert as you would need new cars, blocks and cleats on each side.

I think your plan is feasible however inserting three holes between each of the existing holes could be a concern. Why not just try one for this weekend and if it seems fine you could always add the other two?

Mike,

What brand of system do you have on your J? I am thinking that your genoa/jib may be about equal in size to my Jeanneau Arcadia. 220# for my 100%, 155 is 345#. I would assume a 4-1 to pull forward?

This is more of a "what do you have?" different question than original to see if an equal will work for me.

Thanks
Marty

Do not recall the manufacture off hand. I believe it is factory installed with boat though.

From the car a continuous loop goes forward to a double block, back to car and again forward to double block. This is the 4:1 purchase. From there comes aft to a cam cleat on side of coachroof (where a spin downhaul is often located) and then back to single block on aft of track and forward to aft end of car.

Works extremely well and easier to use than most oter adjustable car systems I have used including on a Peterson 37 and a C&C 99

Well,

An update, the new holes I drilled, worked reasonably well, today, the old tracks came off, new schaefer tracks went on. I remembered I had some Schaefer cars thinking they would fit my Goiot track, I was wrong, so 3 yrs later, I am using these cars with new tracks, some Garhauer fiddles that the Owner of Fishery supply showed me when in the store a week or so ago, so may have some pics of how it turns out later tomorrow. If the 4-1 system does not work, I did get Schaefers race track, which has 3 holes per 4" of bolt holes, so even then I will be better than my old setup.

Look forward to seeing photos of the new setup.

[blt2ski]

here are pics of new setup, hopefully they are visible enough.

cleaning after removal.

aft to front

Front to rear including small tracks for 110

very front of track

very rear of track and carr and cam cleat to hold the pulling end of the line

under side of deck, with new 3/4" or 2 cm washers vs the old washers that were maybe 3/8" and sless than a cm in diam.


Currently the front fiddle is held onto the ubolt of the shroud. The rear is bolted to the carr where the push/pull lock pin would be. I need to cut this bolt a bit shorter so it does not interfere with the genoa sheet.

I am hoping that by installing the new tracks farther forward I can use the far most setting for reaching to downwind legs with the 110 on windier days for cruising or crewed racing when it is too strong to use a bigger jib or the spinnaker.

I am sure like a lot of things, the playing with the setup to see how well it will work will be the fun part!

May have time to try it this weekend, but more than likely in a week during a race of all places to test it out!

Looks good Marty-

Might want to cover or round the corners on the forward end of the track, so that the corners don't catch or chafe the genoa fairlead control line.

I'm waiting for the end pieces that were not in stock when I installed them, Should be in tomorrow. I need to cut off the bolt ends for the car fiddles more than the end of the track. IMHO!
