I crappie fish out of a Ranger R80 Sport which is 18 ft long with a 150hp and it is just about the right size for the wife and me most of time. You know how it is with wifes, sometimes a 100ft boat would seem too small. I personally would not go with anything any smaller for the type fishing we do. We spider rig most of the time. The Ranger gives a great ride and we have really gave it some good poundings on places like Grenada and Pickwick. Best of luck to ya.
