My guess is the wind changed the speed of your presentation making it either too fast/slow and or too deep/shallow depending which way your trolling or motor mooching. Another thing might be that after the morning bite the fish often move deeper and you are not keeping up with them. Like one of the others said your best bet is to charter that boat or one like him. His boat kinda sounds like Gary Krein's from "All Star Charters". Gary is a great fisher and often uses a flasher/coyote spoon setup. He can be reached at 425-252-4188. You will never regret hiring a pro for one trip due to the amount of fishing information you will learn like proper lures/bait setups, speed, depth, structure etc. This is true for both marine and river guides. Just ask around and get plenty of recommendations cuz like anything else there are good guides and bad ones. Good luck!
