I did find a PDF I used for free diving... You exhale into it to blow it up so it is a start.
Yes, I have a Hobie kayak with their "Mirage Drive" system, which is operated with pedals similar to a bicycle, which operate two fins under the yak. I read they were designed based on penguin flippers, they sort of scissor back and forth.
You can push one pedal all the way forward, and the fins lay flat up against the hull. You can also pull the whole assembly out easily if you want for beach landings, but I don't find it necessary in the conditions I normally see. It has a regular kayak paddle holster on the side, so in shallow water I put one pedal all the way forward and use the regular kayak paddle. The paddle is also there as a backup in case the drive system breaks, but my drive system has been durable and dependable.
If I lived in an area with surf on the beaches, it would limit launching options, because I would have to launch from protected bays or rivers. I would probably fish rivers and back bays more come to think of it. Once you are out on the water, fairly large rollers aren't a problem for me, so long as I pay attention, especially when I am oriented broadside to them. You get splashed a lot, but any small watercraft is like that. I have the "Revolution" model, which is fairly slim side to side, and I sort of shimmy my hips when the rollers are big, and it's fine. It's sort of fun sometimes, I occasionally can catch a little bit of a surf ride on them.
