here's what i have heard recently from a friend who manages a liveaboard out there, and another friend who went the beginning december 05:
- many more mantas this year, but there seems to be more spottings at hin daeng, hin mueng than in the similans/koh bob/koh tachai/richelieu rock
- visibility is a bit down compared to the norm
- some sites have suffered (north point or christmas point for example), but tons of fish and corals, east of eden bommie is as beautiful as ever
- seems that diving has resumed outside island #1 which had been closed for years, or at least some boats have been diving out there
personally i have dived out there most of the time with scubacat (7 or 8 times now) on their boat called scuba adventure. it's managed by PJ a mad swede who does a lot of underwater videography. (pj's blogspot
it's a mid range boat, there are more luxurious boats out there, but there are also many many cow boy operations, especially now that a lot have suffered from lower than normal tourists last year and this year. (note that though they are camera friendly as PJ takes his video rig on each dive, there was no camera table last time i went, so it's working in the main room on the low table).
(i have no commercial interest in scubacat.)
of course you have other boats like the ocean rover, and the mermaids (my experience with them and their "salesperson" in patong is less than glorious and happy but that's just my experience), and also sea bees seem to have a good operation as well.
