A sailing friend of mine needed a vertical 'Little Hawk' style wind indicator that can be mounted at the front of their monohull dinghy i.e. where the painter is tied.

I found Kieran's design. But when printed, I found the balance was very tail heavy, so I have modified the design to get it pretty close using 'standard' resolution printing.

The vain should fit directly onto a Little Hawk mount, but I found that 4mm knitting needles (cut down to size) are the same diameter shaft.

I have also published a retain clip (of my design) which can be used:
