Check the listing for details. Catalina Foredeck Openable Deck Window 18-1/2 x 18-1/2. Color: Silver, Condition: New other (see details), Made in United States. Listed at 150.00 USD. The Catalina Foredeck Portlight is an openable window made of high-quality, high strenth material designed specifically for light with thick rubber outside edge and soft inside seal rubber. It is strong to support a heavy person. The manufacturer part number is S2 44 LP. This window offers easy access and ventilation for the foredeck. Originally sold by Catalina Sailboat at $380, this openable deck window was never installed. It was ordered for my Catalina 38/39 ft boat to replace the main operable foredeck window. It has a grey tint to shade the sunlight and, when open, provided fresh air. It provided natural light, privacy and security when closed. It can be picked up near Glenview, IL, Pleasant Prairie or Menemomee Fall, WI, or shipped.
