In Portland I was paying $192 for a 32' double, plus $10 to read the power meter plus the power used. About $20 more a month for single slips.
I have the boat in Tacoma for a few months this year and am paying $207 plus $12 plus power used. The $207 includes tax. This is in an out-of-the-way marina near an industrial area, though not a bad marina. They want considerably more ($75 - $150) for the nicer places in Puget Sound.
We leave 'em in the water year around here in the NW.
