A guy came down to me tonight looking for a uni joint.
He had just purchased a 'beginner' board locally. Never windsurfed and naturally full of enthusiasm to get on the water.
The person he purchased the board off said that the board would sink down below water when uphauled and then rise up to the surface as it got going!!!. Board and rig 'sinker' from 1983.
Well there goes another potential windurfer

That gear should be on the tip.
