Welcome to the site Svenne.
Please help us understand exactly what you are looking for because there might be several different "covers" available when someone first buys their boat.
Do you mean the "bimini"? (made of fabric which is attached to a metal frame and is used to provide cover from the sun in the cockpit)
Do you mean the rear "enclosure"? (made of fabric which is usually also attached to a metal frame, and is used to enclose the rear of the cockpit)
Do you mean the "mooring" cover? (made of fabric, does not usually have a frame, used to keep dust/dirt/water out when the boat is not being used)
Do you mean a full cover (made of fabric and covers the entire boat from bow to stern. Exactly like a cover for a car)
