Not an apples to apples comparison. The envision is more of a "sport cruiser" than the velocity or 25 ol.
Velocity will give you the most speed oit of these choices, very fast single engine boat. Very little room in cabin or deck.
The Baja 25 ol performs fairly well all around, and is safe and stable for new perfomance boaters. The 272 adds creature comforts, and a molded swim platform not found on the outlaw. also has more daytime room than the 25.
The envsion will have the most room...deck and cuddy, it will also be the slowest with that SB engine. I would guess the envision to be a 45 mph boat with that power.
