I was chatting with a friend of mine familiar with the East Coast tug scene and he tells me that McKeil Marine from Hamilton is planning on adding two new Z-drive tugs to their fleet and may be here around May.One of the tugs is called the Pacific Tempest but i'm sure it will be repainted and re-named.Heres a link to it
