Siuslaw salmon questions

Warning: many, many noob questions incoming.

I've been fishing all my life, and just got my first kayak this spring (Old Town Sportsman 106, paddle), but 1) have never fished for salmon from a boat; and 2) have never fished the Siuslaw estuary. Since I'm in Veneta, that's the easiest water to target.

First noob question: I know that there area LOT of power boats out there in September and October, and I've heard that a lot of power boat guys kinda hate kayaks and the people in them. I've fished the kayak enough - quite a bit, actually - to know that my max sustained trolling speed is about 2.5 mph. Will that get me run over, or waked, or yelled at? And what to do when I hook a fish; let the thing take me for a Nantucket sleighride, PBs be damned, drop anchor, or something else (keep in mind that I'm paddle only, so with my hands full, I'll be drifting)? Any other thoughts on living peacefully with everybody else out there?

Second noob question: I'll start out with spinners behind a 360 flasher, and according to the charts, the Siuslaw from the jetty crab dock to the 101 bridge isn't very deep, with a couple of exceptions. With that or similar rig, do you guys flat line, or add a cannonball, and if the later, what weight do you usually use? I run a Garmin Stryker, so if I mark fish, i can try to adjust, but what's the default approach?

Third noob question: if wind and tidal exchange are too fierce, or the PB traffic is just too hairy, has any body tried anchoring and casting as an approach, and if so, how did it go?

Thanks a million in advance.

Don't worry about the PB and Guide boats, almost all are real chill and respect kayaks, I rarely give more than one or 2 'the finger' on a normal day.  lol.
Also, do not let a salmon pull you around, that is the path to having a seal take your fish.  Tighten your drag, pull the fish pedaling in forward or reverse, fight it hard and fast, get it to near the kayak and let the netting happen when you get it's head coming into the net. If it isn't hooked good, you will lose it anyway trying to net, so fight them all assuming they are hooked good and line is strong.

I mostly troll the Siuslaw with a 6oz cannonball on an 18" dropper, sometimes 8oz, sometimes 4oz. 

never felt a need to anchor-  when coho are in (late September) and putting on a jumping show, carry a spinning rod and cast for them when you see that.  All around the 101 bridge, along the dune below it, above 29 marker, above the RR bridge...jumping coho hit spinners.  2 well known areas to target Chinook with spinners or mooching herring, especially at high slack, are the area below the RR bridge and also just above where the N. fork comes in, a deep area above the barge dock there where the river comes over along 126. 
Check the tides for Florence next Monday, I'm planning to launch at EWP on the incoming tide, a few hours before high and troll a spinner upriver but the important goal is spending an hour or so at high slack trolling or drifting a herring below the RR bridge. Might get lucky on the way up or down river but the key to the day is that magic hour in the deep hole below the RR bridge where nooks that rode the incoming tide from the ocean might pause and need a snack. lol

cheers roger
