Companionway Vent using Port Visor

[keneasley]

I wanted to add a rain-proof vent to my boat's cabin.
I cut a 3/4" piece of Azek PVC board to fit the middle dropboard.
Then I cut a 4" x 12" slot in it for ventilation.
Then I added a screen to it and mounted the 14" Port Visor.

The result is a good-looking, completely rain-proof vent that allows significant airflow.
Much better than cutting slots into the dropboard.
And the Port Visor is very strong and not prone to breakage.

I also use the Port Visors for the portlights. They are mostly rainproof. A wind driven storm will cause some rain to get in but many times I can leave a portlight open. These are also very useful for fixing a leaky portlight until you can get around to removing and rebedding it. They sell them online at SeaWorthyGoods.

Great airflow solution. You are correct. Cutting angled slots in a dropboard are nearly useless for airflow. I did that on a previous boat decades ago, it looked neat but the airflow was minuscule and driven rain still entered the companionway. Thanks for sharing.
