I have the Sea Eagle 340x kayak and have used it several times. It is extremely stable and very easy to get into and out of. It is slower and more work than a good touring kayak especially in windy situations but I love mine for certain conditions. I also have a 17' Seda Ikumma kevlar kayak which is not as stable and harder to get into and out of but it goes like a dream. Each have their uses and you need to determine how you want to use them and your storage available. The Sea Eagle goes in the back of my Honda C-RV easily whereas the Seda needs to be put up on top and it hangs out the back.
I like using the Sea Eagle for a day on a lake where I can wander around and stop in a pretty place and read a book or just relax. I can move around in the kayak while out on the water to reach the bag on the front where I have my snacks, water and a book. You would need to really work at it to tip it over. According to advertising, dog claws are not a problem.
