This is Iceland's decomissioned whaling fleet, four ships in all. They were retired in the mid-eighties and sit as relics of another, more ignorant era.
But Iceland's involved in this "scientific" whaling business, isn't ?

This is a very volatile and complex issue for the nation, and one not to be easily resolved.
