Boat is overall too light? I'd say if there's not enough mass to it compared to the size, it may handle oddly. A bandaide fix to this would be add a small amount of weight or use bigger batteries.
Slack in the rudder? If you have any slack (and especially a decent amount) it could cause it to handle funny. I had a 34" mono that would run over 90mph but would never go past 70 until I removed all the slack from the steering.
Trim tabs. I know this is a cat but I saw trim tabs in the pic. Real cats have trim tabs but on models it's not common practice to put trim tabs on. Actually it's frowned upon. Not sure why as it seems a fast cat may be able to go even faster with it by making the hull "longer". But anyway, if you have them adjusted down too much I'd guess that could make it dance.
Strut position. Is the pro angled down, neutral or up? I'd recommend (just an edujamacated guess lol) putting it at neutral to begin with. If it blows over then adjust the tabs down a tad till it stops blowing over. If it's running too wet and the tabs are up or neutral then give some positive on the strut.
Try moving battery position to see what it does.
Prop. Maybe the prop doesn't suit the hull. Is the prop sharp? It should be.
Neutral: in line with the bottom surfaces of the boat
Positive: pointing up (exaggerated because it won't be pointing up but just a tab)
Negative: same as above except the prop facing more so downward. Or trim tabs. Same difference
