lazyjack boom attachment

Hello,

I was thinking of installing lazyjacks on my boat. I was considering the simple ropes and rings configuration I saw on some website (ropes are passed through rings and when retracted the rings come cleanly to the mast with each rope slightly tensionsed).

Now, I have a sail with a track on the foot. Would it be ok to tie a string as a collar around the boom, in between two carts to serve as a base for two (one on each side) of the lazy jack's rope ends? This would assume that one of the cart will block the travel of the collar string if it is a little loose.

I feel that the forces exerted on the lazyjack should not be excessive to this setup and I would avoid having to drill the boom.

Am I wrong?

Thanks

Do you have a track along the base of your boom into which you could slide guides? Then you do not have to tie around the boom. This photo shows that setup.

Re: lazyjack boom attachment

Alas no, I have an old school cylindrical boom with fittings riveted or screwed in.

Re: lazyjack boom attachment

The one concern I would have would be chafe from the sail foot slides. But that might be reduced by stowing the lazy jacks when not in use. Hardening and easing the outhaul could lead to some chafe if the lazy jack lines make contact.

Re: lazyjack boom attachment

OK, If I need to replace the strings once a year or so, it's not a big deal. I could also put some grease on them to mitigate that issue.

I'm not so worried about the outhaul. I usually don't touch it (the boat is not rigged for fine tunings, it's an old C29).

Re: lazyjack boom attachment

Looking at your avatar my first reaction was 'lazy jacks on a laser??.. but I see we're talking about a Col 29.

Not real clear on what you want to do.. is the foot of the main on slides/slug in a track? Are you planning to pass the lazyjack line between the sail and boom and contain the sail that way?

If it's a bolt rope main that won't work, of course. If the above scenario is in fact the case then you might be able to do that.. some versions of the stack pack idea are entirely contained in the sail (the 'cover' is attached to the foot if the sail, and the whole works is slid into the foot track)

But tying anything around the boom itself means you'll need grommets in the sail if it's boltrope, esp if you want some outhaul adjustability.

Re: lazyjack boom attachment

My laser is my other baby even though I have not sailed her for long time already (and I miss that).

I just made a quick sketch of what I had in mind. The lazy jack line is in red and the strings to attach them around the boom are in white. All the other systems are what is currently on my boat.

Re: lazyjack boom attachment

I also realize I could directly tie the two sides of the line together underneath the sail and avoid using the extra string but I wonder if that could hurt the carts when I pull it up somehow.

Re: lazyjack boom attachment

Why not just attach on bottom of boom with one continuous line?

Re: lazyjack boom attachment

I recently installed lazy jacks with the same reluctance to putting any new holes in my boom. There was a good diagram on SailNet describing how to make them yourself that I followed. An added advantage to this is the ability to adjust the mounting points later along the boom should a line continually fowl a batten or something similar. If anything starts to wear I plan to make appropriate repairs and adjustments. If something breaks; oh well!, I'll furl the sail the old way.
