Martin Edvardson Gross. Norway to California via?

My grandfather, Martin Gross was born in Flekkefjord, Norway in 1863. After receiving a good education in the Norwegian schools, he went to sea at the age of 14. He spent six years in the sea trade and sailed to numerous foreign ports. Much of his time at sea was spent working on the Barque St. Lawrence which was owned by unknown parties from Arendal, Norway. On a voyage from Savannah to Liverpool, England the St. Lawrence wrecked off the coast of Fleetwood, England. The ship was lost, but all the crew survived. This was the last long voyage my grandfather went on during his employment at sea. He worked for another year an a half in the coastal sea trade. In 1885, at age 22, he decided to emigrate to the United States. I don't know the date he left, nor the port he left from, nor the ship he left on, nor the route he took BUT sailed to the Port of San Francisco, California stopping just long enough to freshen up and obtain passage on a coastal vessel sailing up the Pacific coast to Humboldt Bay, where he arrived on May 1, 1885. I would like to determine the ship he left Norway on. The ship he left a secondary place on [if there was one].i.e. Hull, Hamburg etc. I believe since he sailed mostly out of Kristiansand that he very well might have left his homeland from that Port, although it is my understanding that it was a small harbor. San Francisco Port records are hit and miss. They weren't the best to start with, then most records compiled earlier were destroyed in the 1906 earthquake and ensuing fires. They have few passenger arrival or ship's lists available, especially on line which I am limited to use for researching. I have tried to learn more from the Emigration records in Norway and have been unsuccessful. Can anyone help? Thank you for your patience, Helen Mc nee Gross I would also like to know more about the Barque St. Lawrence, which I have been unable to learn anything about.
