I know both the Sea Bird and Sea Lion. These are not the ships which is identified as Clelia II.
I looked at a number of URL's for the history of her build, ownership and rebuild.
The link on her being grounded is at:

" The same ship had to be pulled from the rocks off the peninsula during last season’s summer season, which lasts from November through February. The Clelia II was also grounded twice during its season in the Arctic this past fall." This is a bit curious, since I found another link which clearly showed that the Clelia II was used for Great Lake tours this summer and fall.
The ship which accompanied her back is noted to be the National Geographic Explorer, which is run by Lindblad expeditions. Her itiniary fits. She is Bahamas registration and Overall Length: 356 feet.
She was previously a ferry along the Norwegian coast for Hurtigruten.
In that incarnation, she carried approximately 300 passengers and 40 automobiles. She was converted by Lindblad in 2008 to a high lattitude cruise ship. Looking at the two ships, there is considerable difference in the hulls and freeboard etc. even though the size is not that much bigger.
The most recent posts show Clelia safely back in port.
