I do keep a sailboat in Greece and I have not heard of Anemos ( meaning WIND ) . Please let me know where they are located and I can easily find out through my contacts for you. Meanwhile beware: Most charter companies are excellent, however there are some unscrupulous outfits.
Please also advise when and where your plan will take you. Avoid August. There are over 21000 sailboats roaming the islands then and the meltemi in the Aegean is a vicious wind. Elias
