no such thing as a dirt cheap race sail
just an occassional bargain if you happen along at the right time.
i can only guess it is made from kevlar..aramid, or some other short life expectancy race cloth.
hey, if it looks good on your boat, and will only cost a couple hundred boat units, i say go for it.
treat it well, keep it clean and it will last longer than the 5 yrs the sales guy said (be wary of "sales guys"..) .
see the sail on your boat before any cash changes hands.
By three methods we may learn wisdom: first, by reflection, which is noblest,second is by imitation, which is easiest,third is by experience, which is the bitterest.
