Yesterday (march 27, 2015) I I found a large and beautiful sailing yacht in Marina da Gloria, Rio de Janeiro, Brasil. I have not been able to confirm yach's name, but it looks like Ahimsa (ex Aglaia). Another beautiful SY has been in same place a week ago, that seemed to be Drumbeat (ex Salperton).
Looks like you hit the nail on the head with Ahisma http://www.marinetraffic.com/en/ais...pid:384529/_:4637491b087e5673b5172ed34d1f40dd Drumbeat is now North of there so you are probably right about her too! http://www.marinetraffic.com/en/ais...l:DRUMBEAT/_:4637491b087e5673b5172ed34d1f40dd The pic of her looks the same as those on MT of Drumbeat.
