Inspect Those Lines!

Yesterday I was looking over my Flying Scot jib.  I had not removed the 2:1 jib sheet harness at the end of the season.  On first glance it looked new but as I was about to place it with my jib sheets one of the blocks moved towards the opposite side of the brummel loop.

Hidden under the frame of one of the blocks the line had frayed through one of the two loop strands. 

Imminent Loss of Jib Control

I'm sure this would have failed at the worst possible moment, when one of my Fleet 163 buddies is breathing down our neck as we approach the finishing line!

I'll make a new harness for the upcoming season.

Anyone else have a good "how did that happen" story?

Defect

With a defect like that you may need a new boat...

New Jib Sheet Harness

Here is the new 2:1 Jib Sheet Harness I made this weekend:

Looks great, what did you use for the lines?  I have to replace both of mine bridles as they were to like yours at the end of the season.

 

Used Dyneema

I used 1/8th inch Dyneema and scavanged the blocks from my old bridle.  You can find more detail on my posting at the Nockamixon site HERE.

Bridle configuration

I noted with interest the difference between the configuration in the two photographs. The first, with the frayed line, seems to show that the blocks are close together on a longer leader. The second shows a short, almost non-existent leader.

I had thought that it is best to knot/join the lines about 6" back from the clew to enable cross sheeting.

Does anyone have thoughts on this ?

Lead should be about the same

Julian,

You are correct.  The attachment and crossover for both need to be the same.  The plan to accomplish this on the new harness is to use a separate soft shackle for the lead.

In my case I occasionally change jibs, mostly to not pound my newer sail in heavy winds. 

With the fixed harness lead this involves completely removing the jib sheets, removing the harness from the clew, attaching the harness on the new jib and rerouting the jib sheets.  Most often I inadvertantly add a twist or two in the jib sheet, so need to raise the jib to figure this out.  Then I need to untie the sheet ends to correct the problem and then retie them.

Using the removable lead attachment makes it much simpler.  I just need to lay the new jib in the same orientation as the old.  Then detach the lead and reattach it the same way on the new jib.

Below is how it looks rigged in my basement.
