Cat's usually burn less at planing speeds cause they have less surface area in the water.
They are more stable due to the wide stance.
But they will still pound if the waves are too close together.
Some Cats have displacement hulls, which don't plane at all, and some have semi-displacement hulls which get on plane a little.
Planing is a little slower, but rides better.
If you get a Deep-V and a Cat that are the same length, the Cat probably rides better.
The Deep-V will rock side to side more cause of the V shape and stability. The roll is slower from side to side.
The Cat will snap back upright quick cause the hulls are set so far apart.
I am a traditionalist, I would rather a longer Deep-V hull that can scoot. The longer the boat, the better they take the waves when running. The Deep-V usually has more storage under the deck because of more hull space to put it in.
I don't mind the rocking from side to side when fishing, it gives your bait/lure more action. But slow rolling from side to side can make some sick real quick.
The newer V hulled boats are getting better and better as far as ride goes. New technology makes the very fast and very fuel efficient. You can have boats where the cruise speed is 50 mph or better that get 1 to 2 mpg, which is good for an offshore boat and top speeds run close to 70 mph.
Cats get better mpg, but don't normally cruise at 50 mph.
