Designed by Aborn Smith and built by Trump Yachts beginning in 1981, this compact 20.5-foot sailboat represents classic American small-boat craftsmanship from the early 1980s. The fiberglass construction features a traditional long keel configuration that provides excellent tracking and directional stability, making it particularly well-suited for new sailors learning the fundamentals of seamanship. With a displacement of 3,100 pounds and 1,000 pounds of ballast, the Companion 21 offers reassuring stability for coastal cruising and day sailing adventures. The masthead sloop rig delivers 218 square feet of sail area, providing adequate power for leisurely sailing while remaining manageable for single-handed operation. The boat's moderate beam of just over seven feet keeps trailering practical while still offering reasonable interior space for weekend getaways. The comfort ratio of 19.95 suggests a motion that favors stability over speed, while the capsize screening value of 1.94 indicates good initial stability characteristics. These qualities, combined with the forgiving long keel design, make this boat an excellent choice for families, sailing instruction, or anyone seeking a traditional sailing experience in protected waters and near-coastal environments.
