I lost all my BTC

I use to go fishing at a nearby river that has several small island on it and I thought it would be a great spot to hide the only cold wallet I had on one of them. When I headed tonthat Island with my kayak, a fully loaded ore transport ship passend and when the waves Hit my boat from the side, my kayak flipped. I made it out of the boat and when I got Back in, I noticed my metal wallet was Not in my vest anymore. I also lost my smartphone this way. This means I dont own any BTC that I purchased pre 2025. Thats all. I wont answer any PMs.
