I have a 19ft cc with the cooler seat/leaning post combo. It's really a cooler seat with a back rest which can go back (use cooler as a seat) or forward to be used as a leaning post.
It's not as sturdy as a true leaning post but it does an excellent job. I really like to fact that I can move it back so I can sit on the cooler and have a nice back-rest. Comes in handy when I'm trolling for stripers up here- I simply sit on the cooler and kick my feet up on the console and relax untill i get a fish on
The drawbacks are that it does not have rod holders build in nor does it have tackle storage.
Since I only use the cooler as a cooler on a few trips, I'm going to have a cooler sized storage bin done up in fiberglass with handy pull out trays for my fishing gear and it will have a padded top like the cooler. Figure it should give me the best of both worlds.
