About the American 28 Motor Sailer Sailboat

Designed by Arthur S. Henry and built by American Mariner Industries starting in 1977, this versatile 28-footer represents a thoughtful approach to dual-purpose sailing. The Motor Sailer configuration emphasizes practicality and comfort over pure sailing performance, making it an appealing choice for coastal cruising and weekend getaways. With a shoal draft fin keel drawing just 2.33 feet, this boat opens up shallow harbors and gunkholes that deeper vessels cannot access. The 6,300-pound displacement and moderate ballast ratio of 1,600 pounds create a stable, comfortable platform that won't pound in choppy conditions. Her fractional sloop rig carries 240 square feet of sail area, providing adequate performance under sail while remaining manageable for smaller crews. The boat's comfort ratio of 24.1 indicates a motion that favors relaxed cruising over spirited sailing, while the capsize screening value of 1.73 suggests reasonable stability for coastal waters. Her 6.63-knot hull speed is respectable for leisurely passages. The fiberglass construction ensures durability and low maintenance costs. This design particularly suits sailors who prioritize comfort, ease of handling, and the security of auxiliary power over racing performance, making it ideal for protected waters cruising and day sailing adventures.
