I have an 18 ft. run about with a built in cooler. The cooler drain has a<br />valve that keeps it from completely draining for some reason. Any how I<br />bought the boat used and the previous owner must have never dried out the<br />cooler. From this the set cushion backs above it have rotted out and needs<br />replaced. I am new to boating and want to fix it correctly. One of the seat<br />backs has a curve in it. I am looking for anyone that would know of a good<br />book to purchase so that I can fix this right. Thanks.
