The Sea Pearl 21 Trimaran represents a radical yet functional expansion of the original Ron Johnson design, blending the classic aesthetics of a Herreshoff-inspired coastal cruiser with the stability and speed of a multihull. Manufactured by Marine Concepts in Tarpon Springs, Florida, this vessel is an evolution of the standard Sea Pearl 21 monohull. By adding folding amas (outriggers) to the existing narrow, shoal-draft hull, Marine Concepts created a "camp-cruiser" that can be beach-launched, easily trailered, and sailed in waters too shallow for most keelboats. The boat retains the signature unstayed cat-ketch rig, which allows for rapid deployment and simple sail handling, making it a staple of the "small boat" expedition community.
