But now I realize that the retort "This isn't rocket science" isn't entirely true, but I can explain it without calculous so that anybody who passed 6th grade math CAN understand.
*The volume of your tubes is what gives you boyancy.
*Larger tubes are MORE boyant while smaller tubes are LESS boyant.
*The surface area of your tubes is the amount of area that can be pushed by water, air, or a combination of the two.
*More surface area can be pushed MORE
. Less area can be pushed LESS
*The density of the medium pushing (lifting) directly affects lift and this means air won't lift the tubes, water will, and a mix will lift but not as much at all water.
Legend tubes were designed fat to give maximum lift. They were given 8.5-9 inches of rocker to ride up over waves rather than pencil into them. And they do exactly what they were designed to do...steep drops, frothy waves, pop out of holes, surf and sidesurf.
They're a bucket of fun!
But because they were designed specifically for lift they are MORE affected by (all water/no air) hydrolic features that lift, and when you get a single tube affected by hydrolic lift, the bigger dimeter the tube, the more lift.
And something I didn't mention before. Bigger tubes are more affected by wind. They can be a PITA to row in flat water.
As for who designed the Legend tubes. I think Mike Saywer's "Brown Banana" is an obvious step in the evoloution of the design that took a couple of years to develop, so it's hard to say "this is the point that defines the design."
I ordered my new cat different enough from the Legend design that they didn't put the "Legend" logo on it, but you'd need to carefully measure it to tell the difference. It looks like one and to me it is.
