William Rule Jeatt's service history, reconstructed from the CG Establishment Books (ADM 175) available as free downloads from the National Archives website:
14 Feb 1833 nominated to Lydden Sprout
7 April 1834 to Kimmeridge (ADM 175/6 pdf 129)
31 Jan 1837 promoted to Commissioned Boatman
28 Feb 1839 to West Lulworth (175/6 pdf 360 & 775) promoted Chief Boatman
30 Sept 1851 to Weymouth (175/7 pdf 370) reason 'Benefit of health'
5 Dec 1855 to Whitenose (175/7 pdf 378)
7 Nov 1859 to Hill
12 March 1860 promoted 2nd Chief Officer.
At this point the CG record system changes, and you would need to establish the name of the CG Ship that covers the Hill CG Station to find his career further, but it cannot have been long before he retired.
You might also like to know that he was, like many CG men, issued with a Merchant Seamans Ticket (144,479). On this he gives his date of birth as 25 July 1813, Dartmouth, 5' 9 3/4'' tall, brown curley hair, complexion fair, eyes grey, first went to sea as a boy in 1827, could write, never served in RN. Ticket issued 17 June 1845 at Weymouth.
