After years of waiting for a kevlar boat that I could afford, I now am the proud owner of a 18.5 foot Sawyer canoe. It's old (probably 1975 if the last two digits of the serial no. stamped on the boat means anything). I can't tell what model it is but it's 34" wide at the middle (not tumblehome) and depths from bow to stern are: 16",11.5", and 13.5". I'm curious as to what model it is, but my main question is how to deal with abrasion in the lower bow area. Seems most the solutions involve a grunch pad which I don't want to consider given the nice look of the boat. And I'm pretty careful with my boats, so I won't be running it up onto the beach. Is it possible to repair it by resin only or do I have to use cloth too. It doesn't leak but it is frayed and worn to the cloth for about a 3" run. Any suggestions would be appreciated.
