I'm restoring a 1964 Old Town Otca. After 47 years, the canvas finally gave up. I know it's the original canvas because I bought the boat new in 1964. In addition, it had some rot at the tips of each stem, rot in the gunnals, one cracked rib and four soft spots in the planking where the boat "kissed" rocks. All the repairs have been made and the inside stripped and sanded. I'm ready to varnish and re-canvas. In Stelmok and Thurlow's book, they recommend applying a very generous coat of hot boiled linseed oil and clear Cuprinol to the inside and outside of the hull. If I do what they recommend, I can't varnish for a month. Also, over the years, the inside has darkened considerably. I'm afraid the linseed oil/Cuprinol mix will darken it further. I want to keep the inside as light as possible. What if I varnish. After the varnish is complete, then I oil the outside only. Then re-canvas? I'm looking forward to any and all advice. Thanks!
