I windsurfed a little bit as a kid and then had a taster course a few weeks ago.

I decided I'd like to get into it properly and bought a rig off ebay.

5am this morning at Sandgate I put it all together and had a go. Imagine my horror when I stood on the board and it sank! Like not just a bit, all the way I was about up to my waist and it was on the sand!

Is that supposed to happen or did I buy a lemon? However hard I tried I couldn't get me and the sail up fast enough to get moving before it sank to the bottom.

New board or more practise?
