Hi Alan, I have contacted Rig-Rite, and they are still singing the same song. They want pictures (pesumably close-ups), all the dimensions, and sketches for the jumper assembly.
Seems to me that I could have this made up locally with just the dimensions. It looks like the mast taper does not affect the pattern, and I can make a template at deck level which will fit just fine. It appears that the arms are at 90 degrees. Only other info needed would be:
-type and size of shroud attachment points.
-wire size.
-configuration of spreader tips.
I can't tell from the pics, but do you think the spreaders were made from the standard Isomat spreader stock?
I know it's a lousy time of year to be mast climbing, but I would be happy to underwrite an expedition by an eager, young prospective crew member w/tape measure and camera to bring back the pertinent data!
BTW, are you happy with the placement of the lower shroud attachment points, or do you think they should be lower and closer to the headstay termination?
Let me know what you think, and thanks again for all your help.
