I have a number of chinook days under the belt from 12 yrs in the Seattle area... and I would say there are three options:
1 - estuaries from a boat with a single hander... 9wt minimum, 10wt better
2 - tidewater with a two-hander... 14ft 9/10wt or better
3 - beaches with a two-hander... I would think the Atlantis is as good a rod as any for that task
In your case it seems a good solid stick like the ones Philster and others suggest would do the deed.
The new Outbounds come to mind. They come in a range of sizes. For kings off a boat I might go with a slick shooter running line looped to hi-density heads biting deep into tide rips with flashy herring patterns with a streak of purple and big eyes. It would cast like the dickens too.
A stripping basket is key. Check out Russell Chatham's book... he's done some serious damage in the estuaries.
Keep us posted... I miss having the chinookie on the side of my steelie obsession.
