Killer vessel! I'm jealous. My MK2 Futura definitely has less beam and strapping my Brewer longboard across it is like having airplane wings on the zodiac. I also wasn't comfortable with having the board resting on it's rails, I prefer to distribute the pressure over a larger surface area. I didn't want the boards catching that much wind either. At first I used cut out ethafoam "bones" to cushion them when strapped on the side tubes, but the flex of the tubes appeared to put a bit of stress on the boards. So I made two racks out of Holland Speed Rail fittings and aluminum tubing. The mounts extend all the way across the benches and bolt on to each side so they can handle the leverage of the rack arm. The pipes running across the bench make great lashing spots for other cargo too. The rack arms are easy to remove when not in use, but the bench rails stay in place. Since the aluminum floor section doesn't flex much the racks stay in one plane and the boards are not tweaked even when launching over waves. It sure looks like you have a good system for your boat and I would only comment that PVC pipe is not particularly UV resistant and will become brittle over time with sun exposure. If you intend to use the system you have for an extended period of time I would at the very least paint it or consider replacing the pvc with aluminum. Rack failure will always occur at the most inconvenient time...

the boards float above the tubes

That is helpful to visualize. I think I may use a soft rack variation on my tubes-strapping through the handles and the rub patches on top.

I think I can rig up straps/rack pads that will go on either side, should be enough to strap down a couple longboards on each tube. I'm hesitant to put in anything too permanent, because this is primarily my dive boat--and it already has racks for scuba tanks and the like.

Dang, sure wish I had a bigger RIB! Just be careful if you strap the boards down along the tubes. The tubes flex quite a bit if the water isn't all glassy and smooth, even with a rib. If your board is strapped down really tight it will get stressed. The other issue is tying down to just the handles. It is really hard to keep the boards from flopping around with a single point attachment. I was contemplating adding a few d-rings to the inside of the tube so I would have two points of attachment when strapping down on the tube. What can I say? My old Brewer longboard is a classic and I don't want to trash it, my shortboards aren't that valuable monetarily or emotionally. Give it a try and you'll see how it goes for you. A number of ribs around here have an overhead rack installed. Sort of the t-top type of idea. I would give that a go, but it would be quite top heavy on my little lightweight inflatable. Might not help the seaworthiness of my zodiac?

That is a good point about tube flex. I have a rear tank rack that I could probably put one cross bar on for this purpose-I may try and monkey with it a bit to get two in place. Come to think of it, I may be able to pull out that (it is stainless and removable) rack and put in a wood rack with shelves over the tubes for boards. Probably use the same attachment points.
