Just a follow up posting.
I only managed one day of diving as I was in Oman with a non-diver and opted for Extra Divers out of the Shangri La Hotel in Muscat on 2 Dec (Tuesday).
First dive was to Mermaid Cove. Viz was variable from very clear to small patches of pea soup, but the area was teeming with life. A lot of fish.
Second dive was to Jissa Island. Similar dive to Mermaid Cove but slightly less fish around, but still lots to see.
Surface was quite choppy on unsheltered areas but we started these dives in coves and the surface was very calm making for quite easy climbs back into the boat.
Extra Divers - as always- is a well run operation. Only 4 divers plus DM on our boat. My insta-buddy was a really nice guy on the surface but was overly involved with camera work and didn't seem to be aware that I was his spare air or vice versa. 45' depth isn't much but it's too deep to think that you don't need a buddy. This wasn't the dive ops fault. I was torn between sticking with the DM or staying with Mr. Distracted. I did the right thing and hung back with my buddy. He was also one of those photographers who thinks that his possession of a camera entitles him to hog everything worth seeing without any regard for the other divers with him, but that seems to be a universal problem. Oh well. Another vote for dive with people you know where you have more time to establish rules.
I must say that the diving was surprisingly good. These dives are similar to what you would expect in the Florida Keys, yet there is hardly any dive industry. We were the only divers on both sites. It seems that Muscat is that rare thing in diving today- a hidden gem.
I guess that for European and US divers if you are going to the trouble of traveling that far east, you will often want to go to the Red Sea or the Maldives. Diving in Oman (Muscat or Mussendam) will not be at that level, but it is still pretty damned good. When you factor in Muscat as a great destination for the tourist who wants to see the real middle east rather than Vegas Without Gambling (Dubai), I still don't understand why Muscat doesn't get more press as a diving location. Oh well- everyone else's loss and our gain.
