hi SkunkWORX ,
that are great news! how are those spreaders fixed to the mast?
can they be shiped to china? where can I order them?
I owned 3 marstroem carbon spars in the A-cat the last 6 years and I believe your spreaders are quite simular to theirs, although the marstroem ones are only fixed by one screw in the middle of the mast where you can (within a certain range) can move the arms back or fore on the mastprofile. I furthermore (to lazy sometimes to change the mast to suit a different sail) also added a second rail for the diamond at the end. that allowed perfectly (like you described) changing settings easily by just pulling on the wires with your foot pushing against the mastprofile even with the diamons under tension (which anyhow was much nicer solved and more easily adjustable than on the saarber/ahpc/fibrefoam spars). i strongly believe two different settings are o.k. and three are realy enough. for example 30/45/60 would cover most of nowadays needs?
regards
