The Editor's review of this ship is spot-on, so I won't repeat what she has written. I would like to add some thoughts based on our trip "Among the Great Whales" in February of 2013.
We had a wonderful experience. The up close interaction with the gray whales was extraordinary - and not an isolated event. Every person on the ship had a chance to pet - yes, pet - a baby whale while we were out in the Zodiacs. We saw dozens of humpbacks breaching within 50 yards of the ship and spied an enormous blue whale off the bow. Lots of sea and shore birds made for nice photo ops.
Be prepared: the cabins are tiny. If I stood with my arms outstretched, I could touch both side walls at the same time. I'm 6'4" and bumped my head a dozen times a day. Not much storage space with two people in the cabin, and ya gotta love the toilet inside the shower stall!
Cabin 202 was a good choice. A little forward of midships, pretty stable on a blowy day, no engine noise. Adequate A/C plus a window kept things comfortable. Tall people will feel cramped anywhere on this ship, but it was worth it.
