Daylight and fresh air

On-board bedrooms are often equipped with a porthole. You can ventilate your room and ensure a sufficient supply of fresh air with a casement window. The other purpose of a porthole is to admit daylight into the room.


Apart from its functional function, a porthole may also be a true eye-catcher on your boat. The porthole windows of ARC Marine have a beautiful, traditional look.

Porthole window catch

In our product range you also find a porthole window catch. With a catch you may close and secure the window in rough conditions like towering waves and rain. This product is available in a chrome and a brass variant.
