Sister Stay installation on 43DS

[sirromcd]

???We are considering installing a "sister forestay" to allow a second head sail to be used without removing the original furling genoa.
The "sister forestay" will give the flexibility of hanking on a #3 or storm jib when working to windward in heavier weather without removing the furling head sail.
This configuration will also allow twin head sails to be utilized when running downwind in trade wind conditions.
We envisage that the sister stay will normally be stowed alongside either of the side stays and deployed as required using a turnbuckle or Hy-field Lever onto a fitting on the bow just aft of the existing forestay fitting.
A tang for fixing the top of the "sister stay" will be fitted to the mast just below the existing genoa halyard. The additional load should be supported by the existing backstay setup.
A new halyard sheave will be installed in the mast just below the tang.
A "sister stay" has several advantages over an inner forestay, including the fact that there is no requirement for running backstays, nor is a stay required which passes through the forward cabin bunk into the keelson of the yacht.
Does anyone have any experience with this sort of adaption in a Jeanneau 43DS or similar vessel?

high I am going through this process at the moment on my 43ds and am waiting for my surveyer to go over it with me for the through deck fittings i am planing to fit this just behind the windlass which should allow a rod type chain plate to just pass the windlass motor through the chain locker bulkhead with very little intrusion into the forward cabin i considered placing it more forward on the bow roller plate but there is not enough room for a double eye without getting a bit to close to the furling gear i also consider having a bit more deck to work with a + if in any sort of sea i am hoping to view this with my surveyer in the next couple of weeks and will let you know where we decide to go with it

Hi Windspeak,
sounds like a plan. Look forward to your post after speaking to your surveyor.
I have seen a similar installation to your descrition but cannot remember whether they have runners.
Cheers
