I am putting a masthead kite on a 24foot Farr727 quarter tonner. Will add a masthead jumper stay / strut system. Attached below in black ink is the current mast and standing rigging. In red is shown the new jumper system - stays and spreaders. Stays masthead to chainplates via jumpers and main spreaders. New jumpers same sweep back as main spreaders. In blue is additional optional diamonds. Has anyone done this successfully - in which case used just the red items or both red and blue. The present standing rigging is 5mm forestay and caps, 4mm lowers and backstay. I was going to use 3mm wire for the new jumper and maybe diamond stays - does this seem ok? All advice much appreciated.
Thanks in advance. rgds
