Hi
Does anyone know or have a rough idea how much it costs to put a lazy jack systems with all lines led aft onto a Moody 27 ?
Thanks for any help
 
Difficult to say without more detail of what you hope to achieve. Biggest cost are blocks, organisers and clutches and the number of these you require depends on how many lines you want to lead aft. For example, simple systems just have main halyard jib halyard and topping lift, but you can also have reefing - single line or two line, kicking strap and spinnaker gear taken aft. The lazy jacks themselves are cheap, but you may also want a stack pack for the main.

Suggest you look in the Barton catalogue to see what the options are, decide how much you want to do and then price it up.

It really depends what the OP already has on the mast or spreaders as the top anchor point - that's likely to be the cost. It won't be much for a couple of cleats and monel pop rivets top put on the mast to tie them off - need a decent pop riveter, but he could hire that or borrow it.

Mine are set up with blocks at the moment, but the problem is each one distributes 50% of the tension, so once you've cascaded a few together the aftmost line to the boom/stack pack doesn't have much tension in it. I'm thinking of replacing the blocks with splices this winter to deal with that, so it becomes only the cost of the line. I'm undecided between hollow braid http://www.force4.co.uk/8700/Liros-Lazy-Jack-Rope-6mm-Silver.html or smaller diameter dyneema.

I have hollow braid, why dyneema

Smaller diameter for same strength.

OK, it's a cruiser but engrained racing habits are hard to ignore and I've raced a good few times with someone who did wind tunnel tests on the drag from lines attached to the mast and the effect was quite significantly worse when the line wasn't tight to the mast and it went up with the diameter - can't remember if it was proportional or worse than that - (which is why we always made sure the spinnaker halyard, uphaul etc were firmly put back to the base of the mast asap after a spinnaker drop).

So just trying to minimise the drag of the lazy jacks.
 
Give Paul Carey a call. He is a good rigger and knows Moody's inside out. Based in Swanwick but its end of the season so I am sure he would travel for a half day's job. Mob: 07749 829539.

He sorted mine out for a very reasonable cost. He went up the mast on the main halyard, sorted out the fixings and blocks and spliced everything up - all in one Saturday morning.

If you take the lazy jacks forward to the mast (tight as you say) when when you're sailing then the extra drag isn't significant - and if you don't then thicker lines will have less tendency to cut though the sail...
 
You don't need blocks in the lazyjacks themselves. I used stainless steel rings (about £1 each I think) but some people just splice a soft eye instead. I have two blocks at the top (on the spreaders) and the lines then drop down to clam cleats on the mast. So the hardware cost is negligible really. Just a few metres of string and a bit of time.
 
You are going to be at the mast when lowering the main to fold it neatly as it's lowered so why spend extra for lines aft and risk more tangles?

K.I.S.S. rules.

On a 27 footer you only need braided fishing line, thin and strong, a few rings so have full adjustment for the first version, you can splice them later when you have properly set and sorted.

Best system is raised on a spare halyard just prior to dumping the main. The whole thing is gathered up stuffed in a bag at the mast base when leaving the vessel.

No wind on lazy jack because it's not 'fixed' to the mast.

It's not rocket science, it's common sense.

Good luck and fair winds. :)

I know. I've done that in the past on other boats and it has worked well, but now my boom is 6.5m long with four attachment points each side, so it takes a lot of grunt to set them up each time to get enough tension in the aftmost, which is why I rarely adjust them. Might be better when I try splices rather than blocks.

Good advice for the OP though.
 
My hanse 312 came with lazy jacks with plastic rings & they have lasted 10 years
I use 6 mm nylon line bought as a 1kg reel for a tenner there are 2 pulleys on the spreaders
The tension is not very great
Once adjusted they stay tied to a shackle at the base of the mast all season but i take them off when laid up
My sail bag was made by Lonton & Gray for £ 200 3 years ago as the first one gave up the ghost
If you get one make sure you have the zip starting from the mast end. that way you do not have to go to the end of a swinging boom to start the zip & work back to the mast again
I also have internal straps fitted so that in rough weather when i drop the main i can strap it & sort & zip up later
The straps are actually a ball & loop system pre. Set to take the weight off the zip so zipping is easier as well
If you want i will post a pic when i get home--- assuming this F9 goes through soon. i did not realise how boring Boulogne is in October. B rough in the marina as well
