good to hear you like the site.
langebaan in december is very good. i really liked it there! about the direction. – look at the google maps to see how the wind is coming in. the wind is coming from S, SSE, sometimes SSW. So you could say it’s almost sideshore on the kitebeach, but after the launching area the beach/bay makes a turn to west, so after launching and you go downwind it feels like offshore. but at the kitebeach it’s basically sideshore.
in langebaan you have a rescue boat. i think it belongs to some school. so speak to people around there how it works. they are not there all the time but most of. and in the evining if you decide to kite longer they probably are not there any more.
i didn’t need a rescue, but i think they charge something per rescue as everywhere.
in shark bay the water is not really deep so you will not really worry about rescureboats. it’s cool to practice as you can stand most of the time in the lagoon as far as you don’t go out verrry far. shark bay is absolutely beautiful. you will love it :)
so, i hope this helps!
