I've been using a Sony RX10 IV, it has fun zoom and supposedly can take some salt spray. It comes with me in the Kayak all the time, and I am careful to avoid getting salt on it. It's been a lot of fun, and probably the one joy out of COVID lockdown for me was buying this thing and tooling around on it. To be honest some days the photos are more fun than the fishing, and particularly so if the cloud and sun action is shaping up nicely and there's some cool animal stuff going on.
After a while you might figure what your camera (or photographer) is not all that good at. For me I needed an image stabilization, good tele, fast shutter speed and super fast autofocus. AND i needed to screw round and take a bajillion photos to see what worked and what didn't, and that also includes post processing, framing, sun angles and so on. So looking at the pics on big screen later was really interesting...
Perhaps one thing that changed is the camera forced me to be way more observant particularly on framing.
