We were sailing back to Rockland when all of the sudden this 100ft. plus long sailboat / ship appeared out of nowhere pretty much from behind us. We never even saw it coming. A half an hour later we caught up to it on it's mooring and sailed around it for a good look. You could park our boat on the deck and it wouldn't even have been in the way. On the main sail boom it said Isladia but I think that's a place and not the name. Even without the sailboat this would have been a nice shot of the Owl's Head lighthouse.
