If you really want to catch a shark and don't care what kind, just fish for halibut
. Leopards, angel sharks, shovelnose, batrays, anything but halibut will hit.
I would be very careful chumming for sharks from a kayak. Catching T sharks is easy when they are around, you don't need to chum. A mac or a plug dragged around will get them. Just be careful if you hook one in the tail with a plug. Don't get bitch slapped and keep the hook out of your own body.
Makos are a whole different problem entirely. I've reeled in two small ones to the kayak, and seen a few more closer than I would like. Not cool. Anything over about 50# can get scary fast. They like to chew on things, like swimsteps, kayaks, or whatever happens to be near them. They often charge the boat to see what hooked them. When there is chum in the water they get excited and will chew on anything.
Both species tend to jump. Let them run when they are green so they aren't jumping near you.
