Last contact with LD was on 2nd/3rd May, 48 days ago. No way that was another Lady Domina, surely there can't be two people in the Caribbean
with such bad taste in names! We don't even know that was the date of departure, in fact we know pretty much nothing about the boat apart from a load of tosh from someone who has such a capacity for reading too much in to things that he thinks a floating sofa is a vital piece in the jigsaw.
It's a long voyage, especially in a tub like the LD. Not beyond the bounds of possibility that she's still out there. If not, well, the Atlantic is pretty big and very deep, nothing we can do about that. Any useful information in this thread has been eclipsed by the useless conjecture from the OP and others, and the only meaningful lead of the VHF
contact was dismissed by our hyper-experienced OP as being a boat with, if I remember rightly, a 'different number'. I give up.
