I know there might be some previous threads on this topic but wanted latest views on getting Freedom 235 vs 255? Looks like seating options are similar but is there more space between back facing port seat and bench? I feel like in 235 it is hard to have people face each other or knees hit. I am looking for picnic boat in east coast bay area with a few small stretches of open ocean. Also, it looks like 255 has larger fuel tank but does it have same fuel efficiency as 235? Thanks
