Why the need for comps?
I got hooked on windsurfing because I loved the feel of flying effortlessly over the ocean powered by a silent wind, feeling the board react under my feet - I like surfing but the buzz I get from it (approx 5 minutes per 3 hours in the water

) is what I get all the time windsurfing.
I had a sail at Doran's a few months ago, no one else out, I hadn't sailed for a while, it was sunny, board and sail were perfect for conditions, I hit about 28 knots max, but I felt like registering a PB in the category of "personal satisfaction". It was just a great little session.
I've never really been a competitive person, which is why I gave up team sports and dinghy racing, and got into windsurfing, the challenge for me is a personal one to find the best enjoyment (for me) out of boardsailing in the prevailing conditions.
Sure the GPS thing is great to see who can go the fastest in all categories, and I don't have anything against those who want to be the tops in the categories, as long as they don't lose sight of why they actually enjoy windsurfing in the first place.
As for wavesailing comps, (and never a wavesailor I'm not qualified to comment, but however...) I wish I took up wavesailing when I was younger, it must be the best feeling carving down a wave face and utilising the power in the sail to carve back up, and down again, etc etc. I love watching it, and everyone who does it is a winner in their own way, why the need for a competition? Does it recognise who had the most fun?
Anyway, that's just my perspective, happy sailing everyone!
