Hi John,
I'm back from my trip on the Solmar V and am working on photos, an interactive tour of the boat, and trip report which will be online in a couple of weeks. I would certainly consider this trip as a warmer water alternative to Galapagos (water temp 77F). We had what the crew called a "down" week, but I still had many one-on-one encounters with mantas and several times with many dolphins. We always had plenty of Silkys swimming under the boat. On one dive, my dive buddy and I had two mantas swimming with us while dolphins were dancing just behind us and Silky and Galapagos sharks could be seen swimming at the edge of the reef and under the boat. It was sensory overload! I didn't know which way to point the camera. Several other divers also spotted a Tiger shark. We didn't see any whalesharks, but five of them had been spotted at Roca Partida just two weeks earlier. There are also lots of white tips.
The diving was similar to Galapagos in the underwater typography. Most parts of the Socorro area were even a bit prettier. We did see a huge school of hammerheads but couldn't get as close to them as we did in Galapagos. We didn't see any sealions. In Galapagos they were following us around everywhere. Also in Galapagos the whalesharks are seasonal. I didn't see any during a May trip, but saw several on each dive during a July trip.
I personally would rate Darwin and Wolf islands very high on my list of places to go back to, but I would also go back to the Revillagigedo Islands in a heartbeat (don't ask me how that's pronounced!). Here are a few of my shots in QuickTime movie format. All the manta shots were taken with the 10.5 fisheye and dolphins were taken with the 12-24. All taken with a D100 in a Light & Motion Titan housing which once again performed flawlessly.
Have a great trip, where ever you decide to go.
Bonnie
