I liked the Thorfinn as well. We didn't like the food, and the hot water in our shower was hit or miss. We were on the upper deck and apparently whenever someone showered in one of the lower deck cabins they got all of the hot water. The boat isn't purpose built, so the dive deck isn't as deluxe as the other livaboard we were on, but it worked.
The guides, and all of the rest of the staff were excellent. I'd gladly go back.
The boat is old, and very seaworthy. I'm not surprised that she's the one that survived the storm undamaged.
