just been playing because I know a folkie who lives on a boat in Upton.

Just one boat could be described as swimmer.owned.beginning amidships or you could be stern and sprouts.shallower.lookout both somewhat memorable for a narrowboat.
And at the prow trump.bookmark.skyrocket - you can have fun with this!

As I found when using what3words on canal locations, I got curious coincidences like wharf.

So where where is your library or doctors practice, or police headquarters? And what do they spell out?
