I was there for a week in June 06. The local wind effect was crazy, the forecast would be 10 knots the wrong way, but all that meant was it was only really going to blow 20 knots the right way. Lots of 4.0 and 4.5 sailing. It's dead offshore and pretty flat on one side, quite onshore and waves on the other side if it's been windy, so not great wavesailing compared to Australia, but decent jumping I guess. Not much to do there, you basically live out of the one taverna, but if you're there to sail it's perfect. The hire kit was JP/NP and reasonable enough.

I was there in 2002, (cant believe it was that long ago!) I didn't stay at Prasonis but had a hire care and drove down from Lindos a few times. (I also sailed on the northern end of the Island) I was there in June (supposedly the windiest time of the year) although I didn't get much wind. It was really hot every day though like WA hot and dry. Think I used a 6.2m and another day I used a 5.8m but then the wind picked up and I could have used smaller.

The Taverna on the beach there is great. There were 2 hire places there when I was there, but that may have change now? Here is a link to one of them. I have also added a photo and there are a couple more in the photos section. It is a great place to visit and we did lots of exploring on the non wind days.
