Shark Encounter on Family Boat Adventure

was on a huge bot with my dad and brother. The bot was apparently mine and it was this old, all rusted iron, but clean and purposefully like that, almost yacht. James wanted to drive so I let him. Me and my dad were having a beer right by him from the top. Don't know where we were going but we were in the ocean and there were a few other boats and we could see land on 2/4 sides. We decided to go swimming so all jumped in. I saw something in the water, a floating piece of kelp or garbage or something and then I thought I saw a fin flash out of the water by it once or twice, but it was kinda far and the sun was causing a tough glare. I thought i saw  it again so I got back on the boat to see. It was indeed a shark and we were heading right for it. I pulled James in and told dad to get out of the water! We both pulled him into the boat right as we got close to the floating carcass the bill shark was eating. It didn't seem to care about us though, as it's dinner was already there. Then we kept going and ended up in this beachy harbor area where we saw Lynn Phillips and all her kids but they were all that - kids. We asked if kyle wanted to come on and he said next time but he was literally like 8 years old.
