    Step-By-Step Guide To Replacing Portals On A Catalina 320

    Replacing portals on your catalina 320 sailboat can be a challenge, but it’s certainly doable with a diy attitude and some elbow grease. Follow this step-by-step guide to replace your portals like a pro.

    Start With Removing Old Portals And Cleaning The Area Around The Opening.

    Before you can install new portals, you must remove the old ones. Use a thin, flat tool like a metal putty knife to pry the old portals off their frames. Remove any remaining adhesive with a plastic scraper, being careful not to damage the fiberglass around the opening.

    Clean the area around the opening with a rag, soap, and water. Use rubbing alcohol or acetone to remove any remaining adhesive. Allow the area to dry before proceeding.

    Discuss How To Properly Measure The Opening For The New Portal And How To Select An Appropriate Replacement.

    Correctly measuring the opening for your new portals is crucial to ensure a proper fit. Use a measuring tape to measure the length and width of the opening. You will want to look for replacement portals that are the same size as the ones you removed.

    When selecting a replacement portal, look for ones that are durable and will resist damage caused by exposure to saltwater and uv rays. Consider purchasing portals with a protective film on the surface, which will make them easier to keep clean and maintain.

    Provide Detailed Instructions On How To Install The New Portal, Including Positioning And Sealing It.

    Begin by positioning the new portal on the frame, making sure that it is centered and level. Use a pencil to mark the position of the corners of the portal on the frame.

    Apply silicone sealant to the frame, brushing it out to create a smooth and even layer. Carefully place the new portal onto the frame, pressing it down firmly.

    To avoid any air pockets, start in one corner and work your way around the perimeter of the portal, pushing down and smoothing out the sealant as you go. Allow the sealant to dry for at least 24 hours.

    Highlight Important Safety Precautions To Take During The Replacement Process.

    Safety should be your top priority when replacing portals. Wear gloves and safety goggles to protect your hands and eyes. Avoid using sharp tools like knives and scissors, which can cause injury and damage the fiberglass. And always make sure to follow the manufacturer’s instructions for the portals and sealant you have chosen.

    By following these simple steps and safety guidelines, you can replace your portals quickly and easily. Enjoy sailing with your new, durable portals!
