Your report brought back some good and some bad memories of Truk. I could have written your opening paragraph in 1999 when I went ot Truk.. looks like the old bus is still going and the potholes in the road got a bit deeper, otherwise it sound the same as when I visited!
We did four days on Thorfin followed by a three night stay at Blue Lagoon, but diving with Sundance Divers. BLH was just in the process of being overhauled and the new rooms were pleasant. Food was good then too
Thorfin is not a boat I can recommend, or would stay on ever again, but I gathered it grounded itself on the reefs recently, so might be out of action now anyway. The only other liveaboard at the time was the Aggressor, and that was beyond my price range.
Having said the above re Thorfin, our dive guide was fantastic, and let us do what ever dive plan we decided to follow.. including going into deco. We oly did two or three dives each day, but spent longer on the wrecks. Unfotunately my camera had got flooded the week before in Oz and most of the wrecks were too deep for my video housing then, so I have very little interms of 'evidence' from the trip - so your photos are a great reminder!
We went in May and the vis was terrible compared to your photos. Looks like winter is a better time to go for good vis.
My favourite wreck was the Shinkokoo Maru, as it was covered in a fantastic mass of colourfull softcorals, but your photos show a lot of sand instead - is it still as nice as it was, or has the coral beeen destroyed?
Good Luck with your future trip. I booked ours via a travel agent in Oz online, as Truk is like a package destination from there, and you can get good flights from Cairns to Guam and Chuuk with Continental.
