Hi, Well for a lack of better terminology I will call it a Porthole awning. The one design flaw that gets me is the angle of the porthole, every time it rains, or drizzle I must close the porthole. I saw a boat that had plastic "Awnings" over the portholes so they only had to close them in a driving rain. Now after this long dissertation the question is??? Who sells them?? Thanks and best regards, Ricardo s/v La Vida Feliz
