I replaced the sheets. Unfortunately the previous sheets were "yacht braid." It has a very soft "hand" so it is easy to trim without gloves. Not so the new sheets.
In the year (I left Norfolk, VA on 11 November 2015) that I have been sailing to and in the Pacific I have been on port tack about 90% of the time due to the easterly trades. In retrospect it was not a surprise that it was the starboard sheet that failed. Prudence required replacing both.
Fair winds and following seas :)
