What is it and how can you tell if it has happend to your boat? I ask this because we ride behind our 2004 sky supreme v208 often with the same people seated in the same places, our stock ballast doesnt work, and on a usual day, normal seating and everything our wake shape seemed very much different from usual, I've been noticing that our wake gets rampier and rampier[rampier a word?] each time we ride, our wake now has this weird double lip thing going on, I will post pics if someone tells me how.

Hull Flex shouldn't be happening on a 2004 boat. Hull flex occurs when the stringers go bad and the boat loses rigidity. Or maybe I am missing something.
