I supposed it's a different Robert Bruce, but this page has an interesting talk of a steamship of that name that regularly visited the Isle of Man:

Robert Bruce, which began as a regular trader between Liverpool, Isle of Man, Downpatrick, and Greenock. The hour of departure from Liverpool depended on the tide, and the passage from that port to Douglas was " the short space of ten hours," At the end of October the Robert Bruce discontinued running till the next season when she resumed her visits. In August 1820, she met with a deplorable accident. "Whilst at Liverpool she was run foul of by the smack Glasgow, and had her mainmast carried away. The mast in falling came down on three members of the band — at that time a passenger steamer was not considered complete if she did not carry a band.

This page isn't quite clear to me, but apparently a ship named The Robert Bruce sailed out of Quebec in November, 1845, hit a hurricane, and lost its masts.

So, those two are on the wrong ocean, since Bruceport and Willapa Bay are on the coast in the southwest corner of the State of Washington. Sounds like an interesting song. I hope we find it. We have lots of people here from Washington State, so I'd say we have a good chance. I think I'll add "Wash State" to the thread title.
