Does anyone have a spare set of Twist Lock Boom clamps I can buy off them?
These bad boys aren't available anywhere within Australia that I'm aware of.
Drop a line to Windsurfing Perth.
I got a set from them a few years ago now, but they are the same as some old Neil Pryde boom clips.
They still may be available, but not sure.
it is very important that you fit the boom arms 'teeth' into the boom tail slots otherwise when you twist the clamps will break.
I might still have some old ones, in case let me know.
I have seen some people successfully replace the worn/broken teeth with O rings.
It may be another brand would fit.
Sliding clamps....electrical tape on the notched or female side, then clamp. Works.
