I had a couple of short pieces of dyneema
left over after making some shackles and I put an eye in each end, wrapped it around a stanchion and shackled a turning block to it that my jib furling
line passes through to align properly with a rope clutch
. My boat
has large diameter lifeline stanchions so it would have take a pretty large shackle to fit around the stanchion itself. Since you lack the length to splice in eyes to both ends, you could wrap it around the stanchion and then splice the 2 ends to each other and shackle your turning block to the loop of dyneema.
