day trips to richelieu rock ?

I keep hearing rumours that there is a dive center in Khura Buri
(thailand, phang nga province) that will do day trips to Richelieu
rock. Nevertheless, I cannot find
anything on the web about such a dive center. Other websites mention
that day-trips to Richelieu rock are possible from Khura Buri, but
provide no details.

Has anyone made a day-trip to Richelieu rock from Khura Buri Pier
(i.e. Ban Hin Lat ) ? Does anyone have any information on a dive
center that can provide a boat and guide to Richelieu from Khura
Buri ?


I know all about the live-aboards from Phuket, I am not interested in
those because I don't have the time. I am trying to put together a
weekend trip so I can drive down from Bangkok with a friend. We
only
want to see Richelieu.
