Hi to you all! I am in love with Bonaire and will be there in January 04. Our group ( all divers) have already found an accomodtaion but an extra friend of us would like to join and stay at Lac bay for six days doing ONLY windsurf. Do you know of some good offers like windsurf (rental or ev, course)+drive+nice accomodotation for 6 days in that area?

Have a look at http://www.WindsurfingBonaire.com which is part of the InfoBonaire site

Right there is the Sorobon Beach Resort for naturists so it may not be right for everyone. Another one is Kontiki Beachclub and the Lac Bay Resort. Any accommodations in the Belnem area would be quite close to Sorobon for windsurfing.

The pages Brigitte pointed out also has links to the 2 windsurfing outfits. Your friend may want to browse their sites to find out what kind of equipment they have available for rental if he has a preference.
