My wife and I spent a wonderful week in the Galapagos on the M/V Evolution in May 2018. We chose it because it looked like a stately boat with nice finishes. The price was in line with the Nat'l Geo ship (maybe cheaper) but smaller and looked nicer to us. The ship had been recently renovated and it looked great. The room was beautiful and spacious. The bathroom was good sized as well. The common spaces (particularly the upstairs bar/lounge area) were big and very comfortable. There was plenty of space for all 32 passengers. The tub was fantastic after snorkeling for an hour. The food was delicious and the staff took great pains to accommodate everyone's needs. The drinks were reasonable priced. Speaking of the staff they were superb. Great personalities and very attentive. The guides were extremely knowledgeable. The itinerary was fantastic, in particular the snorkeling. We'd definitely recommend Quasar and the Evolution!
We liked being in the back of the boat. Much quieter since you don't hear the anchor but if the engine is revved you might feel the vibrations. You get used to it. Spacious and well appointed with plenty of storage. The only negative, and it obviously didn't stop us from giving an overall 5 star review, was that our room (C7) had a funky smell coming from the shower drain after 2-3 days at sea. After about 20 minutes in the room you didn't notice it so it wasn't real strong, but we could tell when we first walked in. I'm told that other passengers haven't complained since so they must have fixed it. The location and layout of C7 was great though. We never heard the anchor being dropped early in the AM and we didn't feel the swells that much.
