I would still bring some sabikis, just in case. You actually can cast them from shore, this is how people snag sardines but also you can drop them off the kayak and catch baitfish(mostly small reef fish) that way. Depending on species of sardine, they won't bite, they feed mainly on zooplankton; they are snagged or netted. There may be some mackerel scad(akule) that will bite flies though. They are a little larger than sardines but good baitfish also. Let me check my tackle box for hook sizing ,not sure off the top of my head.
