With apologies to everyone for this side discussion that only potentially might become relevant to Blood in Baldur's Gate ... having now spent some time getting my bearings with the modern day Baldur's Gate map, it looks as though the only place marked in what might be around the right place to be that boat building is Jopalin's Teahouse. My outside bet now is that the Low Lantern finally became untenable, the owners bought out Jopalin's Teahouse, and merged the two establishments both commercially and physically (and possibly magically). Of course, I'd be more stunned than anyone if that turned out to be true .
Quite funny for me, because last time I was tempted to write (for the joke) that maybe we might get a Blushing Lantern, or a Low Mermaid But in terms of geographical coherence, your theory would make sense indeed ! (and would be creative) And maybe one of the intentions behind this investigation is to help us (re)discover the city and its locations, particularly if Tav is supposed to be a baldurian.
Priests and believers of Ilmater are supposed to be tagged "good". If the guard took the eyes, he might be under cover and infiltrated in the Shrine of Suffering. On a side note, Harborside Hospital is also infamous for some naughty business and traffics.
