One of those mistakes you do only twice (on the same day) - the first and the last time!
Got salivating on the first kitable weekend morning in Perth in over a month and it gone down the drain

Gone out 400 m on the river and on the first turn back the right line slipped from the knot

Wasted close to one hour of good wind before I got to shore and set up again - 15 minutes later the wind died....
