the disclaimer first ......... I am NOT a expert ( but flame away if its entertaining for you)
I had a very broachy quintrex for quite a while an to be honest i really did like the boat it was economical had a cabin and a walk thru screen and hatch set up which i still miss to this day.
But down the face of a wave / swell was definitely ""not my happy place"" if you know what i mean. it could be dead set scarey at times.
I did a fair amount of trial and error to get the boat to behave better and I had a good measure of success and not all of the conventional wisdom in magazines (or on the internet for that matter) is correct for every hull ever made. so you made need to do some trial and error as well.
This is what improved my boat in regard to broaching
Prop
despite all the evidence / theory to the contrary the most difference was a 4 blade prop. now everyone said this was a mistake but it did work.
now it's not a magic bullet and there is some compromise to top speed what id did find is prop grip will help with broaching and would "settle" the boat more (IE 4 blades and also a lower pitch) the blade pitch combination was like putting big sticky tyres on a car it would track straighter and be pushed around less by the waves swell and wind it just had more grip / control on the water.
Wind
Yep take the clears off , i really think this is under rated. as you change the angle of the vessel going over the top of a wave / swell the whole sail dynamic of the cab and canopy set changes and will effect the stability of the boat and direct of force on the boat ( not sure what you do with a hard top )
Weight
heavy and light will react differently so you need to learn your boats character - the one thing that is constant with weight was lower is better get your centre of gravity as low as possible.
my 2 c keep us in the loop on what do and doesn't work.
