The main difference is there is a built in bracket-like extension off the transom that adds the extra foot. It allows the engine to be set back further and gives more room in the boat. From the rub rail down (except for the bracket) it is virtually identical to a V20. From the rub rail up there are several minor differences. All of which are an improvment in my opinion. Molded fish box/bait wells being a huge plus. Good luck.
