The most recent expedition I did on Bilikiki (weekend dive trip on a very nice liveaboard) started with something a little different. We dived on the World Discoverer a cruise ship which had hit a rock in the channel back about 2002. The captain beached it to get the guests off safely and simplify salvage.
She now rests against the shore in about 12m. Her bow and stern are on ridges and you can swim under the hull.
The screw is perhaps in the best order for photos.
The plans for salvage were alas subverted by the locals who pretty much stripped the boat - if you look closely you can see life rings decorating the outside of the house behind the boat, I wonder what it is like inside!
But the best part of the trip was the flight of mobula (aka pigmy mantas or devil rays) on the last dive - fantastic!
Water was a bit warmer than two weeks previously -about 29C.
