The Boat Vent 4, by Vico Marine, is made from a soft plastic thats flexible enough to sew, yet tough enough for any environment your boat calls home. Like the Boat Vent 3, it accepts a support pole for tenting, but is permanently sewn inoffering reliable, worry-free ventilation season after season.

Sewing the vent onto your mooring cover is simple thanks to its removable cap, which allows your sewing machine foot to easily stitch the vent base directly to the fabric; while reinforcement is optional, double stitching is recommended when sewing without it.
