just purchased a 1993 hunter 23.5 and i have a rectangular cover of the same material as my main sail cover and do not know what it is far. it is about 6' x 3' with snaps at the corners. I also do not have any poles for and i have two holes on my slide for my hatch.cover that i do not know what that is for either? I assume they may be related any help would be good.
