craigtoo I should note that .. the EZ jacks design (Arc aft) is easier to tie off on the mast because all the eyes end up in the same place... Slick.

the arc forward.. while usefull for holding the sail near the mast isn't as "neat"

Is EVERYTHING on a sailboat a tradeoff?????

the moral of the story is.. .your Jacks don't HAVE to be symmetrical...!!!!
TUne tune tune...

craigtoo This is arc to bow.

Now.. I have lines long enough to run aft.. I haven't yet.. now I just tie off and stow the jacks on the mast. I have to go forward because I haven't installed all the clutches I need yet...

I'm still tuning this design. It's not perfect. I think I'll get there though.

Another thing I did was to make sure that I used solid red and solid green 1/4 inch lines with padeyes spliced. It looks SOOOoooo Christmasy!! HOW COOL IS THAT!

Anyway...

craigtoo One Side is like this.....



This is "Arc to Stern"

craigtoo I'm experimenting with something...

My lazy Jacks are NOT symmetrical port to starboard.

On the Starboard side I have an EZjacks Copy and on the port side I have a traditional Lazy Jack.

The difference is hard to explain without a pic..(gimme some time to draw one) but the fundamental difference is how the "arc" travels.

If I'm raising or lowering I'll put the bow just off the wind to one side or another.

For raising, you don't want the top battens to catch so I'll push the leech of the sail to arc forward.

Lowering... I start with pusing the sail to arc to stern and swing the bow to push the sail to arc forward.

Wow.. this makes no sense without a pic... or 2

Gimme a minute...or many minutes...

EZ Jax

Check out EZ Jax E-Z-JAX Systems

Great system, priced right (at the time) and came with four lines along the boom.

Good luck.
My boat is equipped exactly this way, except only two lines per side, and I see that really need three. The idea of deploying the lazy jacks ever time I take the cover off, then putting them away again is what I don't like. I have to put bungee cords on the lines to keep the shackles or rings from banging against the mast in the wind. The topping lift on my boat is a poor arrangement too. I need a new sail cover. So what I plan to do is eliminate the topping lift, deploy the lazy jacks permanently to hold up the boom, and have the new cover slotted to close around the lazy jacks.

sander06 Slightly off subject... you mentioned having your sail covers made to handle the lazy-jack. I would suggest that you might consider making the sail covers yourself. It's an absolute cinch and would cost less than $100 in materials. Of course, I enjoy sewing having recovered all of our cushions, made pillows, and constructed canvas covers for most of our teak and other deck hardware. Makes me feel more a part of the boat.

GaryHLucas [QUOTE=chef2sail;369722]Gary we have a double "V" system, which can be pulled to the mast and clipped there when not in use, thus having them out of the way when raising the sail (making it easier) and also negating the need for a specialized sail cover.

Yours sounds exactly like mine, except there is no shock cord, you adjust the topping lines by a cleat on the mast. Maybe the points on the boom where they are attached are located wrong. That might explain why they don't work well.

sailingdog I just modified the boom on my boat to have a better lazy jack system and quick furling system. The modification is pretty simple.

I added four padeyes to each side of the boom. On the 12' boom, I spaced the padeyes 1' in from each end and 2.5' apart. I then ran shock cord through the padeyes on each side. On one side, I added plastic shock cord hooks between each pair of padeyes. To furl the sail, I pull the hook over the boom and attach it to the shock cord on the other side of the boom.

I then attached a line to each pair of the padeyes to make a four-leg lazyjack system that looks like this:




The four legs keep the sail pretty well contained when lowering or reefing the sail. The green line is long enough so that the lazy jacks can be lowered and run forward along the boom and up the mast, keeping them out of the way when raising the main or when sitting at anchor.

The materials I used for this are:

10 Padeyes (two are mounted on the mast just below the second set of spreaders, the other eight are mounted on the boom)
2 Harken micro blocks (attached to the padeyes on the mast)
140' of 5/32" line
6 Stainless steel 1" rings for attaching the lines to each other
20' of 1/4" shock cord
3 nylon shock cord hooks
20 3/16" x 1/4" stainless steel pop rivets
Lanocote

If you drop the lazyjacks forward, the sailcover doesn't even need to be modified. Total cost for the system was less than $200.
