Introducing the 2008 Mainship 40 Expedition Trawler, "Kim Katie III," located in Warwick, RI. This ready-to-sail vessel is a proud veteran of the Great Loop and showcases the sought-after Mainship 40 Expedition Trawler series. Building on the foundations of the popular 39, this model includes numerous unique upgrades. The design team at Mainship skillfully extended the length by three feet, resulting in a remarkably spacious interior and an expanded flybridge. With only three previous owners, the current owners acquired her in Southport, NC, in May 2024. "Kim Katie III" comes with a comprehensive ownership history, including meticulous maintenance records dating back to 2017. Following a thorough mechanical top-end overhaul and extensive upgrades completed between 2024 and 2026, this boat is in pristine condition and ready for long-range cruising adventures.
