I wear my waders right in the yak. Fishing from it is a breeze, just like any yak. Getting out of it is WAY easier than other kayaks. I have never dumped my yak while fishing, but I have while just paddling around. It turns right over and you can hop back on piece of cake.
As far as water getting in...In a normal yak, if water gets in you have to Pump it out. In mine, if water goes in, it just goes back down the scupper holes in the bottom. If you don't mind wearing waders, you have no problems getting wet.
I don't think I have any pictures of me in my yak, but I'll get one taking next time I'm out.
