You can catch chum with hootchie and flasher trolled very slow. Troll slow enough that a Hotspot flasher just wags side to side. 36" or so leader on a dark green or army truck hootchie. Chum seem to be a bit more boat shy than other salmon so put the gear maybe 50' behind the downrigger. Strikes are either very subtle(line goes slack as dog swims along with gear), or it nearly rips your rod off the boat!

BTW, chum are being caught in area 11 right now!
