Beautiful report and photography. You totally nailed a nice mixed bag of fish. I was only in Sitka once, many years ago on a church mission trip with my girlfriend (now my wife) working at Sheldon Jackson college up there. Had a half day off, walked down to the docks and asked some guy if he was a charter captain. He said he was. We struck a deal and went fishing for the afternoon. It was slow but I ended up with one nice 21 lb king.
Sitka is a great destination for an Alaskan fishing adventure. The cool thing about it is it has a real airport, so you can come in on a cheap Alaska Air flight. There's a small town there so you can get lodging and groceries (not cheap though) as opposed to being at an expensive fly-in camp.
Also, at least when I was there, several charter operators were happy to run their boats on an informal open party basis, whereby you're not responsible for $1000 charter if your buddies fail to show.
The bad news is it's getting somewhat overfished. Trips like yours are getting harder to come by, I understand. You did well!
