Similarly, I've found some songs that appear to be the same/similar, so I'll post them here in case they help identify the tune. Just lyrics, unfortunately.

From The Naval Chronicle: Volume 38, July-December 1817:



"Launch of the Orwell, Indiamen"

Go, gallant Orwell! Suffolk's naval boast!
Unfurl thy sails for India's distant coast;
The flag of Commerce hoist on Asia's shore,
Nor dread the billows' roll, the surges' roar.
With wealth full freighted, press the labouring main,
And, joyous, greet Old Albion's Isle again!

"So spake the Genius of her native Stream--
Responsive wood-nymphs echoed back the theme.

The signal's given!--what shouts now rend the skies!
The Orwell moves! the noble ship! she files!

Astonish'd thousands mark the impetuous force,
With which, resistless, she pursues her course;--
Behold the shrinking waves, on either side,
Break, foam, and whiten, 'midst the whelming tide,--
'Till proudly floating on the silvery swell,
Nor winds nor waves against her power rebel.
