I live in Phoenix, Arizona and do most of my kayaking at desert lakes or the Colorado River. Most have rocky shores. The instructions for the Chesse 16 call for a single layer of 6 oz glass over the entire hull. I'm concerned that this might not hold up too long with our rocky shores. I am considering either adding a 3" wide fiberglass strip from bow to stern at the keel and/or a second layer of 4 oz glass on the bottom. My plan is to finish the entire boat bright. I'm wondering if the 3" strip will wet out sufficiently where it will be seen at the bow, or if it would look funny.
