Our 10.5' rib/15 hp 2 stoke would plane with 4 adults. We sold the engine and went with a 9.8 hp 2 stoke because the engine was so much lighter and we didn't usually have 4 people in the dinghy. Planing with 2 adults and the dog is no problem. Three adults takes some effort and it has never planed with 4.
We use to have a 12' dinghy that was real light. That would would plane with 2 adults and the dog with our 5 hp 2 stroke.
A longer dinghy with more water line may plane easier. I think a 100 lb OB on a 10' dinghy plus 4 adults is a lot of weight. Maybe before you buy you can borrow someone's?
