crew list for ships registered in US ports 1844 to 1853

[aweepeep]

My Great Grandfather sailed on US ships during this period.
The ports are - Charlestown during June 1844 to July 1846 and August 1850 to August 1852.
                    - Boston August 1846 to August 1850 and 1852 to 1853.
I have been unable to locate where the crew lists details are held.
I know the ship names, his rank and the individual time periods he served.
Any information would be gratefully received.
