In general, if you are looking at ourboard boats, you are going to get a lot more fishing space on an X foot center console then you would on the same size walk around cuddy.
However, not all 25 foot boats are created equal. Many boats built today have the European Swim Platforms and Bow Pultpits molded into the hull and include them in their advertised lenghts. I've been on a few 25s that feel like 21s and 21s that feel like 25s...
