I took the Nautilus Explorer to Socorro in November 2021. The crew was very good; however, I was not as impressed with the dive masters. They seemed to push the envelope and had us swimming against the current a lot. One dive master swam off and left half the group on one dive! A couple of the guest were very upset with the dive masters! The boat was very comfortable! The food was good. I stayed in one of the cabins for a single occupant. I found it to be wonderful! The bed was the BEST bed I have ever slept in on a liveaboard! I especially liked the night snorkel with the Silky Sharks! That was a lot of fun. One of the crew stood on the stern with a loudspeaker yelling when the sharks would come toward the back of the boat where the snorkelers were. It was a festive atmosphere! Despite not being impressed with the dive masters, I would go back on the Nautilus Explorer again! Sorry, but my photos are too large to download.
