Don't kite at sunset if the wind is low unless your own mates are there and close by!!
Wind died, so my kite dropped. After a good 5 mins of trying to relaunch as I could feel a slight breeze I gave up. Wasn't too far out initially, but by the time I'd given up and wrapped up my lines I was about 100m out to sea, the wind became cross-offshore (was crosshore) and I could already see 3 stars. It was a big beach (Jericoacoara, Brazil) and I was quite far away from everyone. I'd helped a few people that day and all similar stories ended in people paying a small fee for a boat rescue.
No such luck for me, a couple of buggies drove past but didn't see me. I ended up swimming and sort of sailing back to the shore, took about an hour by which time I was really shittin my pants as it was pitch dark and I couldn't even see how far I was, for all I knew I was getting further from the shore! really scary.
lost the rental board too, and equipment is pricey there... but didn't give a goddamn about money at the time.
