Why do Cats not have Trim Tabs?

They don't need them. They basically have two hulls spread out 9 + feet so they dont need to drag tab to help keep the boat stanle and from chine walking or listing side to side etc. Some cats will have a center tunnel tab but unlike trim tabs or planes that use the water the adjust ride. The tunnel tab controls the packing of air down the tunnel to make.it smaller if needed and help lift the boat out of the water even more if it's hopping in a certain speed range

I have a friend on his second spectra and both had a pulsing hop and he is now pitting tabs on it to take that out. I have run with MTI's that had the same hop ?

I have a big Dana marine twin ram tunnel tab on my cat. I rarely ever use it. It makes for a great swim platform to get in and out of the boat. My boat doesn't hop at all. I think with the length of the tab, it makes the tunnel longer causing the boat not to hop.
