There is nothing wrong with a Fish n Dive. They are very good kayaks, and can work well in different venues. I've come across a couple of good deals on them, and was going to grab them but got beaten to the punch. If you are handy with tools and creative, you can easily adapt a good framed seat to it and that will increase you comfort level. The hulls are very stable and robust, and have lots of room for storage on the deck and great access to the inside of the hull.
Go grab it and put ALL of your tackle in it and fish!
Dad took me fishing when I was 10, and I've been pretty much hooked since. He went to be with God on August 14, 2012. I miss you, Dad.
