Seeking a long-range/expedition yacht of 40-45m on behalf of a qualified principal, built for genuine ocean crossings rather than coastal cruising. Naval architecture and range should support extended passages at displacement speeds with strong sea-keeping in open water. 4-5 staterooms required, along with generously proportioned crew quarters able to support a full professional complement for long deployments and world cruising. Open on builder, year, and flag. On-market and off-market opportunities considered.
