This sailing outfit out of Tao http://www.island-cruises.org/ goes to Ang Thong, but I haven't checked if it is a daytrip or overnighter.
I'm almost sure I have seen some other Ang Thong trips advertised on the island.
I have some general info on Tao on this http://tezzasthaiinfo.blogspot.com/2006/12/ko-tao.html page.
