I would say it is for storage but I have had some modifications made by an upholstery shop so that it draws tight all around the boat and straps to the trailer with 8 straps.
As I stated, I place a beach ball just behind the trolling motor to raise the center of the cover so it sheds water. Otherwise it would pool and hold water.
It is a single console if that has any bearing.
