Probably worth another start but I was not in a slip so I am not sure.
We had our boat trucked to this location so we could work on it and put it in the water. While we did not have a slip or dock we did have a hassle free experience. They dry docked the boat without a problem and gave us a great spot to work on it. When we were ready they splashed the boat for us and we fuelled up right there. Parking was not a problem and the Light rail was a block away. So you could get around without a car. I would go there again for marine work. Sorry I do not know about the docks but there were several hardcore fishing folks with small boats there (if that means anything).
What i liked about this place is no one bothered us. We were left alone to do the work we needed. Sometime boat yards can be a major pain in the ass but this place was great.
