~14 months x 4 weeks = 56 weeks X 2.5 days per week.
{~ 3 hours a trip}
I got 140 days {or as some like to use its life expectancy -- about 420 hours} out of two years. probably 1/2 of those days would have been somewhere over 15mph days, perhaps reefed in a bit. But the mylar has separated almost entirely on one side and the threads also appear to have separated from the base other side mostly near the leech ... probably from tacks, and near the luff probably from furling. I am sure a 163 would have not lasted as long on the leech end as the center threads there are showing abrasive fraying.
which I suppose is pretty good for a 3 day life sail.
