    Hey Guys,

    Sorry for the triple post here, but credit for the W32 image goes to Jack Webb, S/V Drifter from the cover of his digitized Westsail Build Manual slightly modified by me to Rhapsody's color scheme and sail number.

    Hi Tom,

    Having reached the limit of my patience in trying to post original images, I have piggybacked a "Lazy Jacks" page onto one of my web sites. This is a diagram and explanation of the system. As I said, the total cost was somewhere around $ 50.00 in 2000 as I only had to buy the carabiners and blocks the rest being on hand.

    This is Werner's image from his site -- nice illustratation....and the stack pak is a real nice bonus to the system. 

    On Pygmalion I find the that the above works pretty good.

    Right click on the image and paste into the reply and resize to fit.

    Thanks for your info. This gives me a lot to work with. What size of rope did you use and how many feet is needed in total? During sailing do you unattach from the boom and stow on the shrouds?

    James,

    I don't remember the exact figure as I had the line on hand but it was probably in the neighborhood of 200 to 250 feet. I used a small diameter three strand nylon of about 3/8". It is the same line I use for the reefing gaskets on the main. The long control line is belayed on a belaying pin and the three jack lines are belayed to the center grab rail abeam the mast by looping them around and securing with the carabiners. I had them on stowed on the lifelines, but the way I am docked now, they were being used as assists when visitors were boarding which made for a very unsecure handhold so I removed the temptation, so to speak.

    I have to remove the jack lines from the boom in order to put the sail cover on so they remain stowed until it is time to lower the main. I can attach them to the boom after I raise the main and sail with them on and have them ready for lowering but normally don't do that due to chafe and wear and tear on the mainsail and jack lines. Since I have to go on deck to lower the main anyway it is just as easy to deploy them then. If you decide to rig this system, you can make the control line extra long so that you can coil it nicely around the belaying pins and it will give you enough to determine the best length since this line will determine how well the main falls into the jack lines. I tied the system together with bowline knots and experimented until the main fell nicely onto the boom and my wife (then girlfriend) did the eyesplices.

    The real truth is that after watching me for about 6 tries, she figured it out using trigonometry, gave me the measurements for the padeye locations on the boom, and it worked perfectly!!! Needless to say I was impressed and married her immediately.

    I will be returning to Florida tonight and will try to post some pictures and measurements in the next day or so. In case you missed the link to the diagram with explanations in the hubub of the previous posts, here it is again. This is where I will post the pictures.

    I have a kit available for lazyjacks.  Look in my Westsail Service Manual, Page A-25.  You might not find that page if you have an old copy of the manual.

    Take a look at www.goodoldboat.com/reader_services/articles/tamers.php  Looks pretty straightforward --- all I lack is time!

    Some thoughts on the lazy jacks. 

    They are really nice when bring the main down! You can even drop it on a beam reach just using the down wind side.

    I use a four part system which works very well.  

    If you use ss thimbles for the slides, use one or two sizes smaller than the line, they will never hit the mast.

    If the halyard for the lazy jack is long enough you can gather them all up and tie them under the cleat on the mast (the one for the lazy jack halyard) when not needed (It keeps them out of the way 99% of the time).

    Lastly: If you have them in the stored location (under the cleats)  tie the bitter end of the halyard line off to the gooseneck (keeps some one from letting it go up the mast :(

    Tom et al.,

    I went sailing day before yesterday and took advantage by taking some photos of the lazy jack rig on Rhapsody. I will post some info and pics in the next couple of days and will move the topic over to the Sail Plan forum if you are still interested.

    Wojtek, I like the mast steps on Namaste.   Can you tell me where they came from and how they are attached (rivets, sheet metal screws, or tapped machine screws)?
