About the Aloha 104 Sailboat

Built by Canadian manufacturer Aloha Yachts beginning in 1981, this 34-foot cruising sailboat represents designer Ted Brewer's focus on creating seaworthy, comfortable vessels for serious sailors. The cutter rig configuration provides excellent sail handling flexibility, particularly valuable for couples or short-handed crews tackling longer passages. With a displacement of 13,600 pounds and a comfort ratio of 27.91, the Aloha 104 delivers the steady, predictable motion that makes extended cruising enjoyable rather than exhausting. The substantial ballast-to-displacement ratio contributes to impressive stability, while the fin keel with rudder mounted on a protective skeg offers good tracking and maneuverability without sacrificing durability. Ted Brewer's conservative design philosophy shines through in the boat's moderate proportions and robust construction featuring fiberglass hull with balsa-cored decking. The capsize screening formula of 1.88 indicates excellent offshore capability, making this yacht well-suited for coastal cruising and blue-water passages alike. While not a speed demon, the Aloha 104 prioritizes safety, comfort, and reliability over pure performance. The spacious 11-foot beam provides generous interior volume, and the 21-horsepower auxiliary engine offers adequate power for maneuvering in tight quarters or motoring through calms.
