While there is not an income tax, there is a pretty bad sales/use tax, which they will hit you to the tune of about 9% when you registar your boat here! Everett at this time is one of the cheaper places to moor in the main tacoma north to seattle to everett. South to olympia is a bit better....... Other wise, figure 7-10 per foot or more per month depending upon where you want to be. for my 30'r, I have had quotes of 250 to 500 a month on Lake washington.
