Good news is yes, but bad news is I can't think of brand names at the moment.
Here, we can get tripple boards that seem to run pretty good at all speeds, they are collapsable too, for storage, nice feature. I, my self, favor the OTTER boats. Not like any boards, actually boats with keels, work awesome at any speed. Pricey though, I think one otter runs nearly 100 clams.
Your problem is one I ran into too. I never really solved it. But I did lesson it. I weighted the outside boards to the point of almost tipping over when not tied on and under way. Used 12 oz of lead on each board, it helped, but I still had problems. You may want to raise the wheels as high as you can go too, would have basically the same effect when underway.
Let us know how it goes! Good luck!
