The nicest example I've seen of the Commander 42 Sport Fisherman is John Even's boat, photos of which have been posted on this site. John's boat changed my mind on which of the 42's I like best - now I like the 74-84 boats better than the later ones. I especially like John's boat because it has the 8V71TI Detroits.
