About the Alden 48 Sailboat

Designed by renowned naval architect Niels Helleberg and built by the prestigious Alden Yachts beginning in 1987, this 48-footer represents classic American yacht-building excellence with Scandinavian design sensibilities. The fiberglass construction combines traditional aesthetics with modern performance characteristics, making it a standout choice for serious cruising sailors. With its substantial 32,000-pound displacement and generous 13,000 pounds of ballast, this yacht delivers the stability and seaworthiness expected from the Alden name. The masthead sloop rig provides versatile sail handling options, while the keel/centerboard configuration offers both deep-water performance and shallow-water accessibility—a particularly valuable feature for exploring varied cruising grounds. The boat's impressive comfort ratio of 38.07 indicates excellent motion characteristics in rough seas, while the conservative capsize screening value of 1.7 confirms its offshore capabilities. These numbers translate to a yacht that's equally at home on extended coastal passages or crossing oceans. The hull's potential speed of 8.16 knots ensures respectable passage times without sacrificing the comfort and security that define the Alden philosophy. This combination makes it an ideal platform for experienced sailors seeking a capable, comfortable cruising yacht with timeless appeal.
