The other problem is the effective low deadrise of the ChrisCat’s overall sponson section reduced dampening and this contributed to that annoying porpoise –but that’s another conversation.



Back on topic –As I mentioned previously the other two are much better examples of the point I am making. I included a couple of visual links in the previous post so why not have an objective look?
