Callisto, a Freeman 30 houseboat, is a project boat that offers a unique opportunity to create a comfortable home or weekend retreat. The vessel has had its engines removed and is available on a secure residential mooring. The interior needs refurbishing, and some form of heating and hot water needs to be installed. However, the wheelhouse and saloon areas offer a lot of potential for conversion into comfortable living spaces. The exterior also requires a repaint and possibly some additional railings to make the external spaces safe. Overall, Callisto presents an affordable option for those looking to create a home or second home, with a freehold houseboat and leasehold mooring.
