Malliemac is a sistership to Tystie. There is a different layout to the forecabin, but the main difference is that Tystie has pivoted bilgeboards, whereas Malliemac has vertically-lifting bilgeboards. The sailing performance will be identical.
Peter Manning saw Tystie soon after she was commissioned, in 2000, and decided that he wanted to build the same. Unfortunately, he took on a project that was too much for him, and while I was sailing Tystie up and down the Atlantic and Pacific Oceans, 85,000 miles in total, Peter was spending years and years struggling to complete Malliemac. He only made a couple of local cruises in the Irish Sea in her. With the same rig as Malliemac's, I sailed Tystie from the UK to Lofoten, and into the Baltic to Finland and back, so Malliemac is certainly capable of doing some good long-distance cruises, in the right hands. Subsequently, I changed Tystie's rig to a ketch, then back to two different single sails, then back to the ketch that she is now. With her second single sail, I sailed single-handed from NZ to Alaska, and with her third single sail from Canada to NZ. The design has therefore been proven to be capable and comfortable.
All of which is a long-winded way of saying that Malliemac was in build from about 2001 to 2012, was hardly sailed at all, and didn't cross oceans; whereas Tystie, her sister, was built very quickly and sailed in all the oceans except the Indian Ocean.
