Later the S.S. Ithaca was identified as the ship in question and it was impounded at Bristol.

And although this story calls the sunken steamer "Hynance",
every other source calls it "Kynance"
But oddly enough, another ship was rammed and sank on the 3rd May in that area by an unidentified steamship. The Talbot (a schooner) was hit off Trevose Head and it's crew were later picked up by The Flying Cloud and taken to Padston.
I did a bit of searching and found that the S.S. Ithaca was in Falmouth on the 2nd May, so to get to Bristol it would have gone past those two locations, in that order. It seems quite a coincidence that there were two different unidentified steamers running into ships that day (though not impossible: I've read that in the mid 1800s you could see three hundred ships from the island of Lundy). The closeness of location and time certainly makes me suspect it was the same ship.
Maybe it was captained by a particularly ruthless sailor who considered it everybody else's job to get out of his way, or maybe it was an ineffectual, slightly comical captain who was just having one of those days.
