Have searched crew and passenger lists on Ancestry and FMP for Thomas John Hampton but no-one fits your description. Also looked at passport applications with no success. Is your Thomas the son of George and Eliza - if so this is the record on the 1851 Census for IOM:

George Hampton 44
Eliza Hampton 44
George Hampton 20
Esther Hampton 17
Eliza Hampton 15
Thomas Hampton 13
John Hampton 43
Sarah Hampton 10
William Hampton 7
Margaret Hampton 4

Here they are in the 1841 IOM Census:

George Hampton 30
Eliza Hampton 30
Mary Ann Hampton 12
George Hampton 10
Edther Hampton 7
Eliza Hampton 5
Thos Hampton 3
John Hampton 3
Sarah Hampton 4 MO

You will see that Thomas had a twin, John.
