I have the same furler, small
CDI, on our Rhodes 22 continental. The forestay on mine, which is heavier than the other stays, runs up the middle of the foil, no separate forestay, although it's a stay-supported mast so there are 8 other stays and two inner stays are attached forward of the mast and hold it up while I'm attaching or messing with the furler.
Here's a couple pics of how its rigged, sorry I dont have a better shot of the furler arrangement. I agree you should have a trigger look at it, your mast might need more support.
Also, next time you are out, try keeping a little tension on the
furling line and the
sheets as you pull out the
jib, dont just let it flop out. I have a big 170%
Genoa, we need to keep it under control when we unfurl it or it will all run out and we'll be swimming, lol.
