When underway you may be surrounded by invigorating, crisp fresh air all around you but take one step below deck and the air quality can be difficult to stomach for even the most seasoned of sailors.
The Lewmar Retro Fit Hatch Vent allows air to be exhausted from the cabin when hatch is closed. Fits to the acrylic lens of any Lewmar hatch. No sealant required. Made of the same rugged composite used in many Lewmar hatch and winch parts. Captive bung closes the ventilator so it won't get lost.
