It depends on the boat and the family really, compared to what you currently have massive difference! This is good and bad, what is the config of the ribX ? For a family boat you want more seats and less stowage for a dive boat the reverse. How many kids? What age? Also will you keep it moored or trailered ?
Is it 2 or 4 stroke motor?
They do some with a rear bench seat that would be ok but others with just a small jockey console which wouldn't
