About the Tripp 47 Sailboat

Designed by the respected naval architect Bill Tripp Jr., the Tripp 47 represents a thoughtful blend of offshore capability and comfortable cruising performance. Tripp built a strong reputation for creating hulls that balance speed with seakeeping ability, and the 47 reflects that philosophy — offering a boat that can handle serious bluewater passages while remaining approachable for experienced coastal sailors. As a mid-size sloop, the Tripp 47 is well suited to couples or small crews looking to tackle extended offshore voyaging or ambitious coastal cruising. The design tends to favor a moderate, well-mannered sailing character over outright racing aggression, making it a practical choice for those who prioritize reliability and comfort on longer passages without sacrificing sailing performance. Bill Tripp Jr.'s designs are generally known for their clean lines, efficient underbodies, and attention to stability — qualities that translate well to a passage-making context. For buyers researching a capable bluewater cruiser with a pedigree from a well-regarded American designer, the Tripp 47 deserves serious consideration as a refined and purposeful offshore sailboat.
