Well, 3.8m inflatable Aerotec is rated to 25hp, so I can see a 3.6m rib having a 40hp capacity. I would think that size rib is primarily aimed as the tender market? If so I would think the high hp rating is to cater for a small boat with a few people weighing it down, taking them to and from a larger boat. With that in mind, with 4-5people on board perhaps 40hp skips the boat along nicely and the weight helps avoid chinewalking, with less people on board it would be a case of being a bit easier on the throttle. To go flat out and not worry about chinewalking with 1-2ppl aboard a 25hp-30hp would be sufficient and give you the speed and fun you want, the higher hp in my view is just to cope with heavier loads. Hydrofoil might help with the chinewalking - I read they do but not used one myself
