Lots of good Aluminum boat manufacturers in the North west. I would look at Alumaweld, North RIver, Boulton, Ed wing, Titon, Almar. All of these boats are proven performers, some of the later on the list are commercial grade boats. Lots of sacraficial zincs on the trim tabs, motors, and transom. A good bottom paint will help as well. Be ready to pull her out a few times a year for maintnance and replacing worn out zincs. I run a Alumaweld 25' formula V, as a charter boat in Puget Sound, My boat is in the water year round. I just keep her clean, and the zincs fresh and she runs just fine. As far as the Fit and Finish, most of these boats come bare bones. You need to add all the options, This can be a little troublesome but in the end you get exactly what you want.
