i would think it would depend on the hull size and wieght. if your talking about a 22' cruiser id say you wouldnt notice much since your adding a smaller percentage of total wieght. with a smaller, lighter hull you would be adding a larger percentage of toal wieght were you will notice it more. i know in my 18' rogers its a big differance when i carry a passenger as apposed to just myself in the boat. from take off to top speed i can definatly feel a differance when i have a passenger.
