The windsurfing video is taken at Doran's road, I can watch the windsurfing and the cat sailing from the balcony. they are both wearing windsurfing harness's so that explains the height issue.

I do know the boat, have not seen it in years though. last time i seen it it looked a bit sad.

The Mast rotation seems to be there but not being used, notice the mast is fully rotated.
