Well, this has happened back in May, but I only heard about it recently - and I think it's a lovely story:
A sailing boat got into trouble at sea and sent out a distress call - which was answered by the Götheborg, a replica of an 18th century ocean-going sailing ship. They came to tow the smaller vessel to a safe harbour.
You can read more about both the Götheborg and the rescue operation on their website - it definitely is worth a visit, if you ask me!
