I'm afraid not. Although Robert Coxon was a sailor!
He was bound at the age of 19 on 20 March 1805 and did 24 years at sea. He was lost aboard Hutchinson's Integrity in 1829.
The records I have are mostly copies of the Trafalgar Square Almshouses for distressed mariners and their families. His widow Mary must have had a very hard life although she did live to 82. Her mother in law also called Mary Coxon lived to 93, dying in 1847!
Curiously the rector who baptised Mary Thompson on 9 sep 1787 was John Coxon, the name of her future husband.
