We had these on our Lipari and they worked really well. We had them especially made for ITIKI in LR by Christophe at Voilerie Klein in La Rochelle. They are fitted at the top with a track attached to the eyebrow and press studs at the bottom. They are black so do a great job absorbing and cutting out the heat from the sun without spoiling the beautiful view from the large Helia windows. They also give a little privacy in marinas. From a distance you can't notice them, as the windows are black looking anyway. As they are set back from the window (unlike the FP factory ones that sit flush) they don't cause any damage by rubbing on the plexiglass. Also as they are not touching the plexi they dont conduct the heat onto the window. Some pictures below. We initially didn't have curtains inside, but I made some in season 2021. We use them if we are in a marina (for privacy at night) or if the sun is low and hot.
