You must forget about the Hatteras. My 33 foot motorsailer will take me around the world in even better comfort. You must compare same size and speed if you like to compare.
In the 70-85 foot range of planing motoryachts, I think the Guy Couach will give you a better ride than most of the others if this is your major concern.
Sorry if I may sound a little harsh, but I will go to bed now at 03.am...
