Same for the H430
My 430 has an oval, non-opening window on the hull, at the same level as similar windows in the main salon. If I were to consider installing one in a boat that does not have one, I would try to get an engineering opinion form Hunter regarding structural integrety, etc, before cuttin' da hole! That said, having visited the plant, the procedure they use is simply using a router to cut out the window opening on a pattern molded into the hull.
