Kerrawyn's wooden hull was built in 1948 or 1949 in Cygnet, then towed to Dunalley to be decked and fitted out for the Young family, who worked her as a crayfish boat for more than thirty years before she passed to the Purdon family of Strahan for shark fishing in the early 1980s. David and Anastasia became her custodians in 2014 and converted the old fishing ketch into a passenger vessel, sailing out of Franklin on the Huon River south of Hobart. Their flagship trip is the Bruny Island Experience: three days and two nights, up to six guests, departing 9am from Franklin Marina or the Cygnet Public Wharf and working across the D'Entrecasteaux Channel to secluded anchorages around Bruny Island, with all meals, tea and bedding included, and guests welcome to hoist sail and haul anchor alongside the crew. The same vessel also runs a Port Davey wilderness charter into Tasmania's south-west and private charters for special occasions, alongside shorter day sails. There is no fleet — one restored 1940s ketch, one home port, and the same two people running it since 2014. Sailing here means working the boat, not watching someone else work it.
