Catamaran Speed Boats Does A 20-foot Catamaran Have A Higher Hull Speed Than A 20-foot Displacement Boat?

Does a 20-foot catamaran have a higher hull speed than a 20-foot displacement boat? - catamaran speed boats

And if so, why?
Would my catamaran faster when I was four legs instead of two?

I'm trying to build a boat very energy-efficient passenger and I hope it goes quickly. Since I do not want to build a ship of 100 meters to obtain decent hull speed with just a little power, I hope to artificially extend the length of the body through my stuff catamaran, which can just work a little - and I wonder whether he stepped on a helmet for extra mention a few.
