Ok Shilshole good choice thats the closest to the SJ's. just outside the locks.

first... this is going to sound strange but you got an extra spool for that fly outfit? if so load it with 6lb mono. buy some fresh herring when you get here... I don't remember the name of the little coffee shop there that sells it... it's been about 15 years since I did this trip with my ex and her dad on a 36 foot Tollycraft he didn't fish so no down riggers and I had to make up the rules as I went along. anyway back to the flyrod. with 6lb line and a troll of about 3.5 knots a 1/4 oz barrel sinker, or bullet if you have them followed by a tight spin plug cut fresh herring becomes a deadly coho killer for the smaller resident coho, the ocean fish (those that are on the return journey) will take it also but you will want to slow down a bit for them. and if you want to get down to humpy/pink land drift with the wind. although at first light I have caught even lingcod with my flyrod rigged this way. biggest fish ever for me on the flyrod (mines a 7 weight...maybe 8) was a 38 inch king that I had to let go (right after the season closed, in the time frame you will be here) caught on the edge of a dropoff in 30 feet of water that went down to 100' wait I'm telling stories again you need info...

so the rig is 6 lb main line, weight, red bead w/ big hole (to protect the knot) 2 ball bearing swivels, for line twist, 4 foot leader of about 10 lbs (for the teeth). the herring should beat like a spinner blade as it cuts the water for coho, and get slower for pinks and real slow for kings, the change in roll is about hook placement. the closer to the top of the herring the faster the beat.

Honestly I wouldn't fish with any other rig behind a boat that size, except maybe a small spoon if the humpys were thick. unless it was equipped with downriggers.

ok the trip you get here and you are on east coast time. so a 330 am to 430 am wake up is not that hard. leave the marina head north along the beach, about what a mile or so up you will hit the fishing fleet that time of year. stay to the shore side of them because they mostly have downriggers and don't want to mess with the flatliners, if you stay shallow and between them and the beach they will avoid you. look for bait zig zag if you get past the point without a fish I would be surprised, but that said the fish are likely to be on one side or the other. not both. fish as long as you want before heading up for me I would say Shilshole to Everett is your best chance for a salmon at that time of year. the whole shoreline is not productive many spots are better than others, but you can look up maps on the internet. Oh I usually fished 60-90 feet behind the boat. also that boat has a dingy I bet. the above mentioned king was in the 8' dingy while mom in law was making lunch. and I was rowing. I could maybe ride from Shilshole to Edmonds or Everett with you. and show you the stuff, but it's all on the internet if you look. and to me making it work was half the fun.
