A small house type establishment that serves as a hang out for people about to board the boats.  There is nautical themed decor everywhere.  Life Buoys, mounted fish, replica boats.  It's all wood inside with a bar as well.  A lot of creaky looking wood too, probably weathered a good bit as the house is old itself.
Boat House, Port
man
a madam and her girls
As Madam of this brothel I expect the girls to toe the line. They will provide an excellent experience for my customers. Or they can go pander themselves from the gutter.
Hey, are you renting any boats sir? Yes please, I am traveling to complete a special request for a client, as I am a smithy. Oh no, I don't work here. I meant do you have any boats that you will rent to us? My bad. No, my mistake, I am not sure where the man who works the Boat House is. What are you here for? Just here with my girls to cross this body of water over to another brothel. That is very terrible, I am sorry. If you wish, you can seek refuge with me and I can train you in the works of a smithy. That might be quite nice, but I am also pretty happy working at the brothel. That is wonderful, I hope I have not offended you. But surely, your children do not? You afford for them yourself, correct? Oh no, can you not see? These aren't my children, they're my girls! Like, you know, my girls that work for me? I am naive, madam, please forgive me. If I might inquire, what are the standard rates? Well... it really depends. For what service are you considering? Is this in your business?
