Fitting Lazyjacks

[Guest]

I am considering fitting lazyjacks to my Jeanneau Sunrise 35 and would appreciate any advice on how to do it or any pros and cons. There are a couple of holes in the top spreaders which look like they may accept pulleys but I am not sure of which type. How do I fit the bottoms of the lazyjacks to the boom, are there different methods.

Many thanks

Paul, if you do not want to cause too much damage to your mast or boom, or go to the cost of sail stow bag, suggest the following setup which we used in the last Three Peak's Race (Tassie).

1 Find a piece of spare 10~12mm rope the length of your boom and affix below the boom using shackles or light cord and stretch under tension.

2 With a small Phillips screwdriver or similiar, insert 4 evenly spaced holes (depending on boom length) along the above rope to allow some 3-4mm cord to be run thru the hole - the idea is not to damage the rope, but just spread apart the layup. This will give you 5 lazyjack tie off points if you use the end of the boom fitting. An alternative to this is to affix sliding nylon sail slugs if you can get them into a bottom track.

3 At the spreaders (upper, if two spreader rig) make up a 600mm length of 6mm spectra with a small loop at each end. Fit off small dinghy blocks at each end. This is then looped around one spreader at the junction with the mast, past the forward face of the mast (don't put it around the back or else you won't be able to raise the main!) and then looped around the second spreader. It is then adjusted around your D2's so that they are level and tied off with a removable plastic cable tie.

4 You then have to construct a cascading system of lazyjacks using small dinghy blocks. The idea is that this becomes self-levelling regardless of the boom angle. The system ends in a single line that goes up thru the small blocks affixed to the mast then back down to deck level - allow sufficient to fully stow the system and still have cordage at deck level. If you have a reefing saddle/hook either side of the gooseneck this is a good place to stow the lazyjacks when sailing for an extended period and reduce windage.

5 At somewhere near the gooseneck you will need to be able to tie off the system - I did fit 2 small cleats here, but removed them when not using the system.

If you then find that you wish to have something more robust, you could then use permanent fittings - this system at least allows fore and aft adjustment and is removeable. I also found that with a fully batted main and no batten cars (ie a bolt rope main) that the last support needs to be very close to the gooseneck to support the weight of the main when dropped.

Simplest way is to use your topping lift. Disconnect from the end of the boom and use two or three lighter cords running from the end of the topping lift around under the boom and back up to the topping lift. The cords can be retained in position under the boom by screwing or riveting small eye plates to the boom.

Sounds like a good system! On mine the lazy jacks hold up the sides of the sail-catcher / sail coat (home -made) that zips up shut. Given the cost of "dinghy type blocks" on this island I found that nylon thimbles are just as good but much less expense. Adjustment of tension is by doubling the last (forward) lines on themselves and using a plain old rolling hitch.

Dont forget to adjust your sail cover to accept lazy jacks.

I just want my boat back in the water ;-(

I am interested in this but I'm afraid I don't understand what you mean. Any chance of a lengthier explanation please.

Me too Burgee!. I've chewed 3 pencils trying to work out how you describe it. Give us a clue!.
