No idea, but for me a 30' boat is a big boat and comes with big boat cost no matter if it is $5k or $500k. There are just big ticket cost, hauling, raising/lowering the mast, slip fees, etc. I went down this path when we decied to move up from a 25' to our 310. We went much newer and ready to sail because like you with my kids we wanted to be out on the water not at the dock. Have you considered a trailer sailed to start with? I don't think you boat sounds bad, but is a lot of projects and issues to address that could very well take a lot longer to fix then you realize. Don't want to kill your buzz, but I learned fast with my kids they want to help, but when ever project takes multi trips to complete they quickly lose interest. But getting out and getting them sailing each time with new roles and skills keeps that enthusiasm going and that was what made it the right approach.
