A detachable curtain coupled to a cover of a boat includes a pliable netting panel, a first sheet member coupled to the top edge of the netting panel and having a first pouch, a second sheet member coupled to the top edge of the netting panel and having a second pouch, a first set of fasteners coupled to the first sheet member and embedded within the first pouch, and a second set of fasteners coupled to the second sheet member and embedded within the second pouch. The netting panel is maneuvered to permit both the first and second sheet members to surround a portion of the boat's cover, thereby permitting the first set of fasteners to engage with the second set of fasteners to support the netting panel in an upright position.
