I have used Seaview Boatyard for about the last 20 years. During that time, they have done everything from simple bottom paint jobs to a complete interior and exterior renovation of an older trawler. Most of the work was done at the (now closed) Seaview East location, but we had the complete renovation handled by their yard in Bellingham. I plan on hauling out at the Seaview West yard, at Shilshole, for bottom paint in the spring.
I happen to know there are several good boatyards in the Seattle area, but being a creature of habit I will always return to the last place where I was well treated and got professional service at a fair price. I can highly recommend Seaview, with a few caveats that apply when dealing with *any* boatyard:
Get a firm, written price, whenever possible, before the job begins. Make sure the work order spells out exactly what is going to be done, and for how much. If you decide to expand the scope of the job, (""Uh, while you're changing those through hulls would you mind installing a new depth sounder as well?""), take the time to clarify how much the additional work is going to cost. Boatyard bills can creep up pretty fast, but the staff at Seaview has always been willing, when asked, to provide advance estimates for any requested or additional work. They have always been fairly close.
When it comes to customer reviews, it's less common to hear from the hundreds of people who are satisfied than from the handful who think they have an axe to grind. After all, the people who had a satisfactory experience got exactly what they expected for about what they thought it would cost- why spend an evening burning up the internet just to tell everybody you were satisfied? It seems like a tiny minority who might feel they were ill used (even if in some cases they were at least partially to blame) will make it their life's work to spread as much negative press as possible.
