Default RE: Boat wobbles alot

ORIGINAL: ddorche

the cg is around 31%,
we played with all the possible options and i run out of ideas. Seams like this type design likes to run wet , based on the way the surface was designed.Anyone here running this hull with good luck at higher speeds?

there is NO set formula as to where your COG should be,it can range anywhere from 27% - 35%,when someone references it should be 30%-33%,this is only an approximation,and could be significantly different than that depending on engine,torque,hp...etc..... return all adj. you made to neutral,and start adding weight to the back of the boat,this can be done with a small bottled water,if too much weight,empty some water out,until you find the sweet spot,and the hull rides "right"...you can then weigh the bottled water and switch to stick-on lead weights,or,you can relocate your engine to compensate..... [8D] all the adj.you made to stinger/tabs should be only 2-4mm,anything more than that tells you something else is outta whack... [:-]
