My family and I have been hunting shark and stingray for years with a bow. What you need is a Recurve bow (I can't stress this enough because the salt air will ruin your compound in just 1 outing, i've see this happen to people.). Fiberglass arrows with bowfishing points, I have found sting-er-ray points work best. You will also need a deep sea fishing rod, preferably a short one about 6ft with a heavy lb test line. The stuff we use looks like small rope not at all like normal fishing line. We do not have the rod hooked to our bow. We also have a landry detergent jug attaches to an arrow that we shoot as a backup so we cann follow the shark or stingray if the first arrow pulls out. If you have any more questions please feel free to ask, once you do this once you will be hooked for life. It is an absolute blast. This setup might seem like overkill but I have shot 100+ lb stingray with this setup before.
