A wonderful piece of history, the Mama C is Rybovich hull # 32.  Many will know the boat as the Tuna Tango as she has a great pedigree with very good owners.  Her original craftsmanship is still intact and she has all the right updates including Cummins power, cockpit mezzanine, water maker, cockpit freezer, cockpit ice and Garmin electronics.
