2005 23.5 ft Calabria Pro-V Wakeboarding Boat with low hours(321). I have owned the boat for over ten years and it has been an excellent boat. Looking to get into a different boat because the kids are grown and we haven't been using as often or use it the way it's intended to be used. Has two built in ballast tanks that are gravity fed that holds 750 lbs of ballast. Open the tanks and it fills in about one minute. When your finished you open the tanks and get the boat up to 20-25 mph and it dumps in less than a minute. We have also built a wake diverter for surfing and have two additonal fat sacs that adds another 750 lbs of ballast. It makes a really decent surfing wave without spending a fortune.Has a custom cover that you can travel with. Trailers well with the dual axle trailer.
