A universal sized mosquito net that fits all brand of hatches. Mounts from the inside of the boat with a suction cup or a magnet. The suction cup or magnet is attached to a string, that are used to keep the net towards the ceiling. It is suitable for deck hatches with interior dimensions up to 300 x 300 mm. The mosquito net is supposed to be larger to cover the "cut out" hole. This makes the net good for variation in hatch sizes. It will also fit different shapes: rectangular, square and round hatches. Folds down to 1/3 size, storage bag included.
