I have fished from a Fishcat 4 for many years. If you need to keep things dry (like lunch), just get a Sealine or similar dry bag. I use basic Caddis fins and they propel me just fine. I should use a fin tether, but never have made or bought them. You don't want to lose a fin. One time I arrived at pond without my fins. It is impossible to move the tube without fins.
