2008 Mainship 40 Expedition Trawler - "Kim Katie III"
Location: Kingstown, RI
"Kim Katie III" is a turn-key, Great Loop Veteran representing the highly desirable Mainship 40 Expedition Trawler series. The 40 Trawler shares the same prestigious pedigree as the best-selling 39, but offers many distinct upgrades all her own. Mainship's design team paid special attention to maximizing accommodations, extending the length a full three feet to deliver an especially spacious interior design and an expanded flybridge.
Only a 3-owner boat, this vessel was purchased by her current owners in Southport, NC, in May 2024. She features a meticulous, fully documented ownership history with all maintenance records available since 2017. Following a major mechanical top-end overhaul and extensive recent upgrades (2024-2026), she is fully turn-key, exceptionally clean, and ready for her next captain's long-range cruising adventures.
