I have a 98 470 Pro II. It had the tubes replaced at the beginning of 2010. The tubes are very similar to the first picture in the original posting and work fine. On that boat the tubes are retained at the bow with screws and washers through the tube skirt. At the bow is no visible external attachment to the hull or the bow ring (like shown in the second picture). At the stern there are two flaps that are screwed to the top of the transom.
The tubes I have also have a fiberglass piece bonded to the tubes that bow which has a cleat and a bow roller.
The tubes were obtained and installed be Annapolis Inflatables. The proprietor posts here as KiwiBoyd. Perhaps he can help you.
The ones you have are pretty close but I wanted to stay away from white tubes. I may end up with them anyway. Spring is right around the corner and I am anxious to get out on the water. Anybody have any other colors? I would love to get my hands on some hypalon tubes but thats just wishful thinking!
