The houseboats aren’t the only thing along the shore of Lake Union. It is still definitely a working waterway and this is reflected by the yards along the edge of the lake servicing the boats. Floating dry docks and regular moorings are filled with boats of all sorts. Some look like they are retired from their original role while others seem to be in for maintenance before heading back into use. I’m not sure how busy the yards are compared to their peak and whether the neighbors are trying to ease them out but they do seem to be needed based on the number of them and the number of boats!
