Jib Stay Length for 4.3

Recommended Posts

Following on from my first post about the DS Tang, when I tried to mount the mast to check things out on my new (old) 4.3 I couldn't raise the mast above the front beam because the jib stay was too short.  Even though I know the front and side stays are the wrong length (5.2ish and 5.3ish metres) none of them had tightened up.  It was the jib stay that was too short.  The cable that attaches to the hounds, via a D shackle, is 480mm long from each thimble contact area.  There is then the standard large swivel for rolling up the jib, and then the jib luff cable attaches directly to the furler with a D shackle. (The jib luff cable is only long enough for each thimble to protrude out each end of the jib and, from each thimble contact area, it is 4050mm.)

My question is, am I missing something that would make the overall length of the jib stay longer?
(I just had a thought, are the two cables attached from the front of each hull to the furler too short? They are each 920mm from each thimble contact area (or 950mm including the long D shackle at each hull end).

Thank you

John

Thank you Pointed Reply, that was a timely response.  I have just placed an order for new front and side stays to be made up for me, but won't be started until Friday at the earliest.  So I have time to adjust the stay lengths.  I have the multi coloured sails for my Mk1 4.3.

Which will be better for my Maricat, making up the stay lengths at 5.5 and 5.0 metres and having a ring 15cm(?) up from the mainsail clew to attach to the boom, or making my new stay lengths to the original lengths for my Mk1 sloop rig?

[What are the old stay lengths anyway, if that is the recomendation?  My current ones are VERY approximately 5.3 and 5.2 metres.]

Thank you

John

Raking  the mast improves the performance and greatly reduces the tendency to pitchpole, but, you must also remove 2-3mm off the rear of the mast step, to allow the mast to rotate, and tuck the rudders under the transom 30mm, to get rid of the weather helm, induced by mast rake. Nobody in our club sails with a standard rig. Hope this helps.
