Love them
I installed 5 of them on my 78 Hunter 30 this summer. The install was very easy, in fact my then 13 year-old son put the last one in. The only cutting I had to do was for the drain cutouts, as my old ports did not have any. Their online directions are very complete.You definitely do want to rent the drilling fixture from them. It is a $100 deposit, they refund $90 on return of the fixture. Just clamp the fixture in place drill a couple of holes, use a couple of bolts to hold the jig for the rest of the drilling. Get a good idea of the cabin thickness when you get ready to start. This will indicate whether you need spacers for the inside frame. I ended up needed them, as my cabin sides were only 1/4",but I just used the drilling fixture to cut spacers for the frames out of white StarBoard.My only complaint about the ports concerns the screens. They are a very nice Stainless Steel assembly, designed to mount between the opening portion and the fixed frame. They have a rubber gasket that holds them in place and seals the joint when the ports are closed. To install them the hinges have to be adjusted to allow for the extra thickness. They can be removed fairly easily, but then the ports do not seal properly with the thickness of the screen ass'y removed. Since I don't always want to have the screens installed, this did not work out for me.Instead, what I did was get some rubber edge molding that fits on the rim of the screen. I put one strip on both the top and bottom. This provides enough interference fit to hold the screens in place when inserted from the outside into the spigot. I can pop them in and out in seconds and they stay very secure.They really improved the appearance of the boat inside and out, and I can actually see thru them, and open and close them (amazing!). Sorry I don't have any photos to post, but there are some in the archives of an install on a Hunter 33. If you get down to Deltaville, my boat is at Stingray Point Marina, slip A-5, adjacent to the pool.
