You are correct kiting at "Fisherman's Hut" sucks but once you get use to these gusty off shore winds you can start having fun and work with the gusts. I had few other kiters with me that hated Fisherman's Hut on the first day, but after they got used to these conditions they did not mind that much especially because of the blue waters and the wind and how warm the water was. We spent 8 days in Aruba and kited "Fisherman's Hut" 3 days. I never new about this law that you can't kite from 10 am to 5pm in front of the Fisherman's Hut!!! Maybe they changed the law, because you had at least 15 kites out in the water every day.
There is also another beach that we went kiting which is near the Mangroves way pass the airport. This was a great place to kite if you don't want to go to Boca.
The reason I did enjoy Aruba is because it is always windy
. I have kited many places and for me Aruba was one of my best top 5 places in the Caribbean because of the wind and because it is very close to the USA. If you go to Aruba for 7 days you will kite for 7 days. Of course you have other places I would recommend in the Caribbean such as Barbados, Puerto Rico, St.Lucia, Martinique and so on but it is not always windy.
Right now I am in St.Lucia with Jeremie Tronet for a Demo and Competition and will be here until the 18th of March. These pictures are from St.Lucia in front of "The Reef kite school".
