You put up a 'red line' and are telling me there is no rocker, that's fine it wouldn't do any good at all .
All the 'steps and BS' will not fix the main problem, only STRAKES will .
The different heights of the 'notches' don't mean BS either, they don't effect the problem .
I would never compare a boat with Bravos to one with #6's, and the bottom mods would not be equal either .
Some one asked about 'removing the notches' and it's not a problem . They are there to 'raise the X', so filling them in would just force the use of 'stand off boxes equal distance that the notch was . OR, mounting the #6 LOWER into the water behind the boat . (notches act like stand off boxes or outboard brackets)
On a 30' + hull the notches do not effect the 'smooth ride', on reasonable waters . This kind of hull is supposed to 'pack air' and that should also improve any 'ride quality' .
PLEASE put a long straight edge (15'+)(I don't care if you use a string) up under the rear half of a sponson, measure where and how much the straight edge intersects or does not touch EVERY STEP trailing edge . Starting with one end of the straight edge at the notch, then going forward .
'Mid speed WALLOWING and GALLOPING' in turns or straight is due to having the steps in the wrong places/heights VS the rear of the riding surfaces .
I too am 'amased' that a few great brand names have come out with 'similar boats' that have 'the exact same stability problems', all around the same time . I remember now that I was out on Havasu during a Hot Boat Magazine boat test . There was a boat in the tests that had been on the cover of HB . The boat had FLAMES coming out all over the cover photos and looked impressive with it's big motors and drives .
The boat had 'uncontrollable bouncing' in the mid range speeds . I'm witnessing this brand named boat do exactly what we are correcting on my buddie's 33' Daytona at the time .
Gross weight requires 'LIFT' to ride on the surface . Leverage also requires lift on a planing surface, or it sinks .
I know you don't always like me but fuck id like to spend a week in your head.
